Question

A ball is thrown vertically upward of 50m/s calculate time

Answer 1

Answer:

5

MY FRIEND HERE IS THE SOLUTION

Explanation:

Initial velocity u =50m/s

final velocity v =0m/s. (on reaching the top)

acceleration due to gravity g = -10m/s2(ball goes against gravity

t=?

Use the first kinematic equation to find t

v = u-gt

substitute values we get :

0=50-10t

-50=-10t

t=5

hope it helps
