I performed a lab using a toy car to go down a ramp that was positioned at different heights. For expample: ramp height = 40 cm, ramp length = 121.92 cm, time car took to clear the ramp from start = .86 seconds, distance car traveled from end of ramp to stopping point = 937.26 cm, mass of car = .54 kg, based off this information..... Calculate the velocity of the car at the end of the ramp just before it starts its horizontal path to its stopping point. PE = KE = (1/2) m v^2
