Time taken by the ball to reach the ground is 1.8s.
<h3>What is free falling?</h3>
When an object is released from rest in free air considering no friction, the motion is depend only on the acceleration due to gravity, g.
A ball is thrown directly downward with an initial speed of 7.30 m/s, from a height of 29.0 m
Using the second equation of motion,
s = ut + 1/2 at²
Plug the values, we get
29 = 7.3t + 1/2 x9.81t²
4.905t² + 7.3t -29 =0
t =1.79871 or −3.28699
As time can't be negative, time taken to strike the ground is approximately 1.8 s.
