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
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
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 😔
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!
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...
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
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
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
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 🙏🙏🙏
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 .
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 😢😢😢
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
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🙏🙏🙏🙏🙏
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
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
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.
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
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 💓💓
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.
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
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 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 😔

Bro on god

Kal hi hai science ka paper😢
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 .
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
The best teacher I have found ,proud of u sir ❤️❤️
Wow Thanks
Who all agree that sir is one of the best online teaches???
Wow ! Thanks
Me their voice is more far better than miss explanation
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
U explaing very well , my physics teacher also explain like u , for more understandation I will see ur video s ,I have also subscribed ur channel
Thanks a lot 😊
My teacher also explains the same
Thank u very very much for helping me in life all the way from Nigeria🇳🇬

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.

Thanks and welcome
One of calmest teacher .. 🤫🤫
Sir,
Your content is very easy to understand.
Thank you soo much
Thank you so much 😊😊😊😊
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
I have no words to say something about you because you are rock .. keep it up and God bless you
Wow, thank you

Thank you so much sir . well explained. I was totally confused but now it's clear
Sir wishing you all the best in your endeavors we really appreciate your service
Wow I wish I had such a great teacher 😍
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
The session was very interesting...I missed the LIVE!!
Thnx a lot sir for clear my douts......
