**A
softball pitcher rotates a 0.250-kg ball around a vertical circular
path of radius 0.600 m before releasing it. The pitcher exerts a
30.0-N force directed parallel to the motion of the ball around the
complete circular path. The speed of the ball at the top of the
circle is 15.0 m/s. If the ball is released at the bottom of the
circle, what is its speed upon release?
