On release 1, a student releases a cart from the top of a ramp, such that the cart travels 190cm before hitting the stopper. The cart increases speed steadily and reaches the bottom of the ramp in 4.00s. What was the magnitude of the cart's acceleration on release 1? The student then releases the cart from a lower position such that the cart only travels 65cm. What was the magnitude of the cart's acceleration on release 2? How long did the cart take to reach the bottom of the ramp on release 2?
