1. Speed of a Baseball:

At professional baseball games, the speed, v, of every pitch to a batter is measured with a radar gun which sends out a pulse of radio waves of frequency f0 and measures the frequency of reflections from the ball.

a. What frequency does the baseball measure for the radiation from the radar gun?

b. What frequency does the radar gun measure for the radiation reflected from the baseball? c. If the radar gun can only resolve frequencies that differ by one part in 10^8, what is the minimum resolution that it can provide (in mph) for the baseball's speed?
