**drwls**, Thursday, October 21, 2010 at 1:42pmThere will be backward tangential acceleration at a rate 0.212 rad/s^2*R, and downward acceleration of V^2/R. Gravity is not accelerating him unless he jumps off.

Add the two accelerations vectorially. They are perpendicular.

**Dave**, Thursday, October 21, 2010 at 5:55pmHi: I need help with the following physics problem. Can you explain it to me? Thank you,

The fastest measured pitched baseball left the pitcher's hand at a speed of 50.0 . If the pitcher was in contact with the ball over a distance of 1.50 and produced constant acceleration, (a) what acceleration did he give the ball, and (b) how much time did it take him to pitch it?
