A windmill style softball pitcher starts from rest and executes a pitch in 0.2 s.  Her arm, from her shoulder(axis of rotation) to her hand, is 58 cm long.  The tangential speed of the ball just before release is 37 m/s.

a)What is the magnitude of the tangential acceleration acting on the ball at the instant just before release?

b)What is the magnitude of the radial acceleration acting on the ball at the instant just before release?

c)What is the magnitude of the net acceleration acting on the ball at the instant just before release?

d) Neatly sketch a diagram showing the position of the pitcher’s arm at the release position.  On this

diagram, draw arrows to indicate tangential and radial acceleration vectors acting on the softball.  Drawthese arrows approximately to scale.  Draw a third arrow to indicate the direction of the net (resultant or total) acceleration acting on the softball.
