Question

A ball dropped from rest falls freely until it hits the ground with a speed of 18 meters per second. How long did it take for the ball to reach the ground?

Answer 1

Answer:

1.8 secs

Explanation:

u= 0

v= 18m/s^2

t= ?

v= u +at

18= 0 + 10×t

18= 10t

t= 18/10

t= 1.8 secs

Hence it will take the ball 1.8 secs to reach the ground
