Step 2: Calculate the ball bearing's horizontal velocity at the base of the ramp using conservation of energy principles. At the top of the ramp, if the ball bearing is released from rest, it will only have potential energy, PE, which equals the product of its mass (in kilograms) times the acceleration due to gravity (9.8 m/sec 2) and its height (in meters) above an arbitrary reference line.

Hit the ball straight up! 2. At the maximum height, v fy = 0. g v t v g t v v a t i h i h fy iy y sin 0 sin But this is ½ the time of flight.
