In her hand, a softball pitcher swings a ball of mass 0.255 kg around a vertical circular path of radius 60.6 cm before releasing it from her hand. The pitcher maintains a component of force on the ball of constant magnitude 30.6 N in the direction of motion around the complete path. The speed of the ball at the top of the circle is 14.9 m/s. If she releases the ball at the bottom of the circle, what is it speed upon release?
