KINETIC AND POTENTIAL ENERGY questions based on data from the lab. 1) Record the height of the ramp above the table top. cm = m ) Record the mass of the ball _kg 3) Calculate potential energy of the ball at the top of the ramp relative to the table top. 4) Record the height of the table. cm = 5) Record the distance the ball traveled from the end of the ramp to where it hit the floor. cm = m 2d 6) Use this equation and calculate the time the ball was in the air. ( = g 7) Record the time the ball was in the air as shown in the video. 8) Was time in the slow-motion video about the same as you calculated? 9) Knowing the time in flight calculated in Question #6 and the distance traveled in flight, use Vx = d/t to calculate the velocity of the ball as it left the table 10) Use KE= 12(mv?) to calculate the kinetic energy of the ball at the end of the ramp 1 1)Assuming our measurements were correct and your calculations were correct, the calculated kinetic energy is almost half that of the potential energy which we calculated at the end of the ramp. Where could some of the energy have been lost? ED acer
