What is the speed upon release of ball at top of circle

Reference no: EM13341730

A softball pitcher rotates a 0.237 kg ball around a vertical circular path of radius 0.527 m before releasing it. The pitcher exerts a 30.6 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 12.9 m/s. The acceleration of gravity is 9.8 m/s2 . If the ball is released at the bottom of the circle, what is its speed upon release?
