50 D) m/s 31) Why does an object in motion stay in motion unless acted on by an unbalanced force? because forces are what stop and A) start motion because balanced forces can not exist B) in nature because motion is the inherent of C) all matter because motion, once begun, continues to D) accelerate 32) A train rolls to a stop along a horizontal track without the conductor applying the brakes. What answer choice BEST explains why this occurred? The train ran out of A) momentum. The opposing force of friction stopped B) the train. The natural state of the train is not to be C) in motion. The force of gravity slowed the train until D) it stopped. 33) The above shows two opposite forces acting on a rolling cart, what can we say is true about the affect of the forces on the cart? It cannot be determined without knowing which man A) is stronger. It cannot be determined because one man is taller than B) the other. The forces are unbalanced, and net force on the cart moves it C) to the left. The forces are unbalanced, and net force on the cart moves it to D) the right.
