Use information from the text to help you answer questions 40-44 Angelina and JP were asked to set up an experiment demonstrating each of Newton’s three laws of motion. They were given two Hall’s carts (Picture below), two inclines, a stopwatch, and a variety of masses. To demonstrate the first law of motion, JP placed different masses in the two carts. He put one cart at the top of the first incline, and the other cart at the top of the second incline. Then he gave the carts an equal push down the inclines. Trevor then recorded his result. 40.
