I was assigned this physics problem and I'm having trouble figuring it out. And don't worry, I have changed the numbers so even if you do solve it you won't be giving me the answer.tongue sticking out smiley

A car of (mass=1.5 tons) rides on the deck of a barge (mass=9 tons) floating in calm water. The car is started, driven at 7.5mph relative to the deck for a distance of 45 feet, and then stops.
a. While the car is in motion, how fast is the barge moving in the water?
b. When the car stops, does the barge also stop?
c. After the car stops, how far has the barge moved?

I think I know how to solve the first one, but I'm having trouble with the second and third ones.
