Explanation:

Given the following:

Height of wall = 19.2 m

Time taken to hit the ground = 5 seconds

Acceleration due to gravity (g) = 9.8m/s (downward motion)

The initial velocity of the object refers to the Velocity of the object at time t = 0

Initial Velocity = g * time

Initial Velocity = 9.8 * 0 = 0
