You could start by saying
You are told your initial velocity is therefore
Now do the same to find the distance
After you have this find
A tennis ball is thrown down from the top of a 120m building with an initial velocity of 8m/s. What is the distance of the ball from the top of the roof 2 seconds after it was thrown?
Acceleration due to gravity is 9.8m/s^2
Please don't use a physics formula to solve this question. Use derivatives.
Show clear steps please.
Thank you so much!
