Question

A pool ball leaves a 1.45 meter high table with an initial horizontal velocity of 6.25 m/s predict the time required for the pool ball to fall to the ground

Answer 1

Time = 0.5 Seconds

Step-by-step explanation:

Given variables:

d = 1.45 m

initial velocity = 6.25 m/s

final velocity = 0 m/s

To calculate the time it takes until the ball reaches the ground we can use the kinematics formula

D = vi-vf/s x t

Step 1. Plug the given variables into the formula

1.45 = 6.25-0/2 x t

Step 2. Isolate t

1.45 = 31.25t

t=0.464 or 0.5 s
