A simpler experiment is to accelerate a ball down a curved ramp, measure the horizontal exit velocity with two switches and predict the landing position as shown below. The ramp is preferably curved so that the ball is not bouncing when it hits the switches. | A simpler experiment is to accelerate a ball down a curved ramp, measure the horizontal exit velocity with two switches and predict the landing position as shown below.
