Question

A ball is thrown upward with a velocity of 100m/s. How much time will it take to reach the ground [ g = 10m/s∧2]

Answer 1

Explanation:

u = 100m/s

g = 10m/s^2

v = 0

v = u - gt

u = gt

100 = 10t

t = 10s

This is Time taken to reach the maximum height.

When ball fall freely from that height it will take same time to come.

Therefore, total time = 20s
