Using a radar gun, you emit radar waves at a frequency of 6.2 ghz that bounce off of a moving tennis ball and recombine with the original waves. this produces a beat frequency of 969 hz. how fast was the tennis ball moving?
Answers: 2
= frequency observed as the ball approach the radar
= frequency observed as the ball recede away from the radar
= speed of ball
eq-1
eq-2
