Question 80

If you throw a dead ball at a baseball, would the baseball not roll as far as if you throw a super ball at it?
Your right. The dead ball transfers less momentum to the baseball than the lively super ball does. That's because the dead ball transfers momentum only one, essentially coming to a stop on the baseball's surface. The bouncy ball transfers momentum twice because it also pushes on the baseball as it rebounds. Overall the baseball receives more momentum (and also more energy) from the super ball than from the dead ball. The dead ball turns much of the collision energy into thermal energy.
