Question

a ball is thrown vertically upwards with a vslocity of 25m/s and at the same time another ball is thrown from the same velocity with h=200m .when and where the ball will meet

Answer 1

ANSWER

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.
