U =72km/hr conv to m/s 72 x 1000/60 x 60= 20m/s V=36km/hr conv to m/s 36 x 1000/60 x 60= 10m/s Using the formula V² = U² + 2as 10²= 20² + 2(a x 10) 100 = 400 + 20a 20a= 100 - 400 a = -300/20 a= -15m/s
I wish I would have this type of teachers in my school... As my physics teacher she just read the chapter and when it comes to explaintion she repeat all word 😔
In last question, Given:- u=72 km, v=36 km, s=10m. Now, Convert these into m/s * 72×5/18=20m/s * 36×5/18=10m/s Using 3rd Equation of motion:- =v*square=u*square+2as = 10*2=20*2+2(a)(10) = 100=400+20(a) = 100-400= 20(a) = -300=20(a) = a=-300/20 = a= -15m/s
Using their equation we have , V²=u²+2as Given 72 km h-¹ and 36km h‐1 converting to m first 72×5/18=20m/s And 36×5/18=10m/s Now we have v = 10 and u =20 and s=10 V²=u²+2as 10²=20²+2×a×10 100=400+2a×10 2a=100-400/10 2a=-300/10 2a=-30 A=-30/2 And we know 2×15=30 so A=-30/2=-15 m/ s You can also do this by not changing into m
The answer is at follows for the last question: u= 72 km/hr = 20 m/s v= 36 km/hr = 10 m/s S= 10 m a= ? v^2=u^2+2aS 10^2=20^2+2*a*10 100 = 400+20a -20a=400-100 -20a=300 a=-300/20 a=-15 m/s^2 As we need to find the Retardation, we need to write the retardation as 15 m/s^2 Do NOT write retardation as -15m/s^2 Thank you!
I am from TN.really IAM very happy listening to u, actually I am very bad in physics,but I want to teach my son.so I am learning,u make me clear enough thank you u r amazing God bless you sir
Seriously 😳 it wasn't that easy.. My physics teacher was teaching me these for last 3-4 days. And I was understanding nothing.. Now your class of just 49 minutes have cleared all of my doubt on this topic.. Thank you sir😊.. May you live long... God Bless you...
Thnxx for helping me and other students After watching your video I solve all question of motion and I am very confused about which formula is taken for question after watching your video my problem is solved 🙏🙏🙏
Waahhh sir fantastic, outstanding and excellent.............. Sir I am learning this topic with 9 months but I didn't understand this because in TH-cam there is no channel who tell this topic in detail but you are the only teacher on TH-cam who explain all this concept very welll, I understand every concept of this sir,,,,,, realy thanks from bottom of my heart 😢😢😢
using V²=u²+2as v= 10m/s u=20m/s s=10m putting the values V²=u²+2as 100=400+2(a x 10) 100 = 400 +20a 100-400 = 20a -300=20a a= -300/20 a= -15 so the retardation of the car is = -15 m/s x s
So much helped ya i can never think That i could get good marks in phyics . Literally I Am proud to have manocha acadamey lessons . Great Work for students sir . Thanks so much🙏🙏🙏🙏🙏
Sir you just make your own learning app and I am damn shure it will be in the top learning of India . Because all over here understand concepts from you only .
Sir just wanted to say a HUGH thank you all the way from Jamaica, your explanations were so clear and easy to understand I really appreciate it and hope to see more videos like this one in the future
QA ans = here we must be analyse this question 😊 here , initial velocity (U)= 0 Acceleration =2 Time =1min =60 second Formula = v=u+at 0 +60 ×2 =120 Here ,answer is 120 m /s
Wow. . i need teacher like u as my uncle as well as teacher .. so its take easiest way to undersatnd my concept . . because concept is power. . . dear sir 💓💓
Sir thanks a lot I was really puzzled with this concept before but after hearing your explanation it was really easy.And I like the way how you explain things easily for better understanding and ur method is totally different fromm other teachers who make it complicated.
O my God Wow!!! I am surprised of your teaching style or method You r blessing of god for us for teaching us in such a practical way. This clears the whole doubt Thank you so much sir Glad to have teachers like u 😊😊😊 There are only few teachers like him
In this pandamic i am not joining my Online classes?? Ur classes are better than my teacher.. Thankuh for all these sir ❤️ May you and ur family become always happy
Happy teachers day sir you are one of the best in youtube may you reach 1 million quick as possible And thanks for teaching us.You are the only teacher whose's explaination is very understanding and sir we don't have to pay money for learning.
Sir this chapter I was not understand ing my teacher was worse he don't know how to teach because of you I am able to o understand thanks a lot your teaching is best
Even byjus teachers can't teach like this you should be at unacademy you are the best in India and for me you are best teacher in world. Thank you have cleared my questions.✨❤️🔥
Legends watching just before going to school to give exam
😂😂true
You are correct bro
Weekend IIT-NEET exam 😂😂Cried night a lot just because not n
Understanding now I'm having exam with in 2 hours
No
Same here after 3hrs is my exam
U =72km/hr conv to m/s
72 x 1000/60 x 60= 20m/s
V=36km/hr conv to m/s
36 x 1000/60 x 60= 10m/s
Using the formula
V² = U² + 2as
10²= 20² + 2(a x 10)
100 = 400 + 20a
20a= 100 - 400
a = -300/20
a= -15m/s
A doubt! why we are converting Km/hr to m/s
Because distance is in meters
Nice one
I wish I would have this type of teachers in my school... As my physics teacher she just read the chapter and when it comes to explaintion she repeat all word 😔
Thanks for liking
Same here..... I can understand your feelings
This for 11 th
Yes😢😢😢
Same here bro
In last question,
Given:- u=72 km, v=36 km, s=10m.
Now, Convert these into m/s
* 72×5/18=20m/s
* 36×5/18=10m/s
Using 3rd Equation of motion:-
=v*square=u*square+2as
= 10*2=20*2+2(a)(10)
= 100=400+20(a)
= 100-400= 20(a)
= -300=20(a)
= a=-300/20
= a= -15m/s
Bhai m/s square ayega last me
Very good
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Thanks bro for helping
I was totally confused in three equations of motion .But after this lecture ,I became confident for my exams after 2 weeks.Thank you very much .
The best teacher I have found ,proud of u sir ❤️❤️
Wow Thanks
Welcome to 2023 somedays before the final exam 🙂😐
up
So tough to remeber😢😢
Bro on god
Yes😂
Kal hi hai science ka paper😢
Using their equation we have ,
V²=u²+2as
Given 72 km h-¹ and 36km h‐1 converting to m first
72×5/18=20m/s
And 36×5/18=10m/s
Now we have v = 10 and u =20 and s=10
V²=u²+2as
10²=20²+2×a×10
100=400+2a×10
2a=100-400/10
2a=-300/10
2a=-30
A=-30/2
And we know 2×15=30 so
A=-30/2=-15 m/ s
You can also do this by not changing into m
why you take 360/18 and 180/18
Thank u very very much for helping me in life all the way from Nigeria🇳🇬
You are so welcome
The answer is at follows for the last question:
u= 72 km/hr = 20 m/s
v= 36 km/hr = 10 m/s
S= 10 m
a= ?
v^2=u^2+2aS
10^2=20^2+2*a*10
100 = 400+20a
-20a=400-100
-20a=300
a=-300/20
a=-15 m/s^2
As we need to find the Retardation, we need to write the retardation as 15 m/s^2
Do NOT write retardation as -15m/s^2
Thank you!
Can we written as acceleration ➡️-15m/s^2
Very thanku , BcZ I was searching how the answer came while all just posted the ans. But u explained as well
Thank u so much
sir, I'm from Bangladesh...
I have never been seen a teacher like you.... Thanks a million sir.
You are most welcome
Thank you sir. I was trying to solve the numericals given by my teacher and this helped me.
Excellent
So, much Thank you sir.

Yeah. He is also one of the best teachers with experience I have ever seen
Yes
Third equation here is different side change in my book,school it is 2as=v²-u²
It's alright both the equations goes to the same answer.Meaning it's the same thing just changed the places.
Thnxx for helping me and other students
After watching your video I solve all question of motion and I am very confused about which formula is taken for question after watching your video my problem is solved 🙏🙏🙏

Thank you, I will
One of calmest teacher .. 🤫🤫
I Accidentally Watched This Video And I Shocked Bcuz No One Can Teach Like You Sir So Nice Of You ☺️^_^
using
V²=u²+2as
v= 10m/s
u=20m/s
s=10m
putting the values
V²=u²+2as
100=400+2(a x 10)
100 = 400 +20a
100-400 = 20a
-300=20a
a= -300/20
a= -15
so the retardation of the car is = -15 m/s x s
Such great and crystal clear explanation 💯
Glad it was helpful!
I was soo worried but 3 questions in I felt like soooooòo confident thank you SOOOA MUCH SIR like you are the best like oh my god

Sir I think the speed of the car is 2 m/sec
As 1 eq told us velocity not speed
The velocity is 120 m
So the speed should be
120m/60sec = 2 m/sec
I have physics exam tomorrow..
Thanks a ton!! ❤️
