Thank you so much Kevin you are an Angel sent from heaven may God bless you 🥺❤️🔥and please Kevin can you please make a video about how to draw this graphs I'm begging you please Mr😭🥺🙏I'm really struggling with it
Kevin ; My approach to finding the maximum heigh was to first calculate the time it takes for the ball to move from it's initial velocity to it's final velocity ( point X ) And it gave me 0.70 seconds I then used the time to calculate the height from the starting point to point X which game me 2.39m Which i added 21m + 0.6m + 2.39 and got 23.99 as my final answer I just wanted to ask if i would be marked wrong given the slight difference between my answer and your answer which is 23.37 ?
hi kevin for q3.3.1 you used the displacement as 21 but they mention that the time being used is from the roof to the roof of the car so would you not also use the displacement of 20.4m which is the displacement from the roof to the roof of the car ?
with 3.4, would the answer not be 192,1N upwards, because since you chose upwards as positive, the 9,8 from multiplying mg would be negative. please correct me if i’m wrong
Hello 👋 In question 3.4 i took downward as negative but my answer for final velocity was positive but it should've been negative because the ball was still going down.Please explain that to me Sir. Vf² =(6.82)²+2(-9.8)(-21) =+21.40 m.s¹
In that particular part of the question we wanted the displacement from the top of building to the top of car. Look at the 21m carefully. They have shown us that it is from the top of building to top of car which is what we wanted :)
Thank you soooo much my good sir I totally rely on your videos 100% when I'm studying.
Clearly when revising with Kevin math and science no need for a text book referral broh u are a book smart himself keep up the great work kev☺❤

Thank you sooo much Mr K. You don't realise how these videos save our grades❤️🙏🏾🥺
You are so welcome :)
This video has been eye opening to new ways (for me especially) thanks so much sir🤝❤️
This question really summarizes the important parts of this chapter! :)

You are welcome😊

No that 0.6 M is from the roof of a car to the ground floor
Ow yess I was also asking my self ,why Didn't he take into account the 0,6m this is because the ball will hit the car not the ground
with 3.4, would the answer not be 192,1N upwards, because since you chose upwards as positive, the 9,8 from multiplying mg would be negative.
please correct me if i’m wrong
thank you soooo much
You're welcome!
Whr can I download this paper Kevin.?.. U a star
Hello 👋
In question 3.4 i took downward as negative but my answer for final velocity was positive but it should've been negative because the ball was still going down.Please explain that to me Sir.
Vf² =(6.82)²+2(-9.8)(-21)
=+21.40 m.s¹
The direction doesn't metter because it's a magnitude besides if u say down is negative then ur Vf shuld be - VF
Where can I download this paper
Why is the displacement not 21 - 0.6m?
In that particular part of the question we wanted the displacement from the top of building to the top of car. Look at the 21m carefully. They have shown us that it is from the top of building to top of car which is what we wanted :)
If u dont mind can I ask where do u live sir
Originally from Ladysmith (near Durban) but have lived just outside Cape Town (Somerset West) for the last 15 years.
