Question

You roll a ball horizontally off of the edge of a table. The instant the ball leaves the table, it is 1.00 m off the floor, and is moving horizontally. It hits the floor after traveling 0.750 m to the right. What was its speed when it left the table? (Show your work)

Answer 1

Using S = ut + 1/2 at² to find the time for the ball falling to the ground.

1 = 0 + 1/2 *10t²

Time t = 1/sqrt 5

Let v be the speed of the ball leaving the edge of the table.

v*1/sqrt 5 = 0.75

v = 1.667 m/s
