Hakeem throws a 9.5 g ball straight down from a height of 2.0 m. The ball strikes the floor at a speed of 7.3 m/s. What was the initial speed of the ball

Initial Speed = 0.8581 m/s

Explanation:

The mass of the ball is irrelevant in this scenario, as all objects fall at the same rate of acceleration, which is gravity.

We can simply use the following equation of motion to solve this:

here, v = final velocity = 7.3 m/s

a = 9.81 m/s^2

s = 2.0 m

Solving for u (initial velocity) we get:

u^2 = 0.736348

u (initial speed) = 0.8581 m/s
