Expert Solution

Step 1

When a ball is projected from height H, the time taken to reach the ball to the ground could be calculated by the second equation of motion as follows:

$S_{y} = u_{y} . t + \frac{1}{2} a_{y} t^{2} \Rightarrow h = 0 + \frac{1}{2} g t^{2} (b e c a u s e u_{y} = 0) \Rightarrow t = \sqrt{\frac{2 h}{g}} . . . . . . . . . . . . . . (1)$
