Explanation: To solve this question, we will use one of the equations of motion which is: v^2 = u^2 + 2as where: v is the final velocity that we want to get u is the initial velocity = 3.75 m/sec a is the acceleration due to gravity = 9.8 m/sec^2 s is the distance = 4 m
Substitute with the givens in the equation to get the final velocity as follows: v^2 = u^2 + 2as v^2 = (3.75)^2 + 2(9.8)(4) v^2 = 92.4625 v = 9.6157 m/sec
