Question

A body is projected vertically upwards with v 20m/s calculate the time taken to reach the max height

Answer 1

hey there here is your answer.........

initial velocity (u) = 20m/s

In vertically projected motion( taking g = 10m/s^2)

max height = u^2/2g = 20^2/2(10) = 20m.

time of ascend = u/g = 20/10 = 2s.

hope it helps...
