Question

A man throws a ball up with 5m/s velocity in 2.5 second calculate intial velocity, calculate the acceleration of ball , time taken to ball to come down and velocity of ball falling down​

Answer 1

Explanation:

Initial velocity of the ball final velocity =0m/s

acceleration due to gravity (g)=−10m/s

2

(upward motion)

By using the formula,

v=u+at

O=25+(−10)×t

10t=25

t=2.5sec.

The time taken for upward journey is equal to the time taken for downward journey.

Therefore, total time taken by the ball =2.5+2.5=5sec.
