You find yourself in the (realistic?) situation of being stuck on a 300-kg raft (including yourself) in the middle of a pond with nothing but a pile of 7-kg bowling balls and 55-g tennis balls. Using your knowledge of rocket propulsion, you decide to start throwing balls from the raft to move toward shore. Which of the following will allow you to reach the shore faster?
a) throwing the tennis balls at 35 m/s at a rate of 1 tennis ball per second
b) throwing the bowling balls at 0.5 m/s at a rate of 1 bowling ball every 3 s
c) throwing a tennis ball and a bowling ball simultaneously, with the tennis ball moving at 15 m/s and the bowling ball moving at 0.3 m/s, at a rate of 1 tennis ball and 1 bowling ball every 4 s
d) not enough information to decide
