u = Initial velocity = 100m/s

v = 0m/s (When it reaches the highest point)

a = -g

t = ?

v = u + at

0 = 100 - gt

gt = 100

t = 100/g = 100/10 = 10s

Therefore, it takes 10s to reach the highest point and from there to the ground it takes the same time

Therefore, the object will strike the ground after 10+10 = 20s
