A student designs an experiment by stacking 1, 3 and 5 books to change the height of the ramp. The surface of the ramp did not change, but the car rolled farther when released from the ramp that was 5 books high. Why?
The higher ramp caused a greater push on the car.
The car would not have rolled farther with 5 books.
The car was pulled down by gravity and received less force from the ramp because the ramp was more steep.
