Repeat Prob. 2.83 for a left-handed pitcher whose release point is D.
Prob. 2.83
The manager of a baseball team plans to use a radar gun positioned at point A to measure the speed of pitches for a right-handed pitcher. If the person operating the radar gun measures a speed s when the baseball is one-third the distance from the release point at B to the catcher's glove at C, what is the actual speed of the pitch? Assume the pitch follows a straight-line path, and express your answer in terms of s: Note that the value s measured by the radar gun is the rate of change of the distance between point A and the ball.
