Question

Zed is playing with a ball on top of a building but the ball fell and hits the ground after 2.6 seconds, what is the final velocity of the ball just before it hits the ground and how high is the building

Answer 1

The displacement of the ball
h=(gt^2)/2
h=(9.8×〖2.6〗^2)/2=33.1 m
The final velocity of the ball
v=gt
v=9.8×2.6=25.5 m/s
