Radar gun problem
Whenever a radar gun states the pitch is 90 miles per hour at what point in the balls travel to home plate is the radar gun evaluating the velocity?
Expert
The measurement is made up at the point where the ball is; whenever the trigger is squeezed and the contacts close to make active the unit. The gun responds in a ‘split second’ by sending out a pulse, catching the return, and then compares the two to find out the difference (that is, the Doppler shift). This is so fast that the ball does not travel much far in the time it takes the unit to respond and evaluate the speed.
