For a fabrication (*sniff*), I certainly am having trouble in a very real way. These are some upcoming test questions. I don't understand the answers. *sniff* Q. An astronaut in outer space wants to play a solitary game of "throw, bounce, catch" by tossing a ball as massive as he is against a massive and perfectly elastic wall. What will occur? A. the astronaut will never catch the first bounce. I don't understand why he won't catch it at least once. Because it bounced? It knocks him down? Or he flies away backwards and it won't ever catch up? *** Q. A 1-N apple falls to the ground. The apple hits the ground with an impact force of about: A. 1 N. Why isn't the force 1N times the gravitational constant? *** Q. A golf ball moves forward with 1 unit of momentum, strikes and bounces off a bowling ball that is initally at rest and free to move. The bowling ball is set in motion with a momentum of: A. More than 1 unit. I thought momentum was conserved. Why is the bowling ball getting more? Thanking anyone in advance.
