Conservation of energy: motion on vertical circle with force

In her hand a softball pitcher swings a ball of mass 0.251 kg around a vertical circular path of radius 59.5 cm before releasing it from her hand. The pitcher maintains a component of force on the ball of constant magnitude 30.2 N in the direction of motion around the complete path. The speed of the ball at the top of the circle is 14.4 m/s. If she releases the ball at the bottom of the circle, what is its speed upon release?

Solution Summary

A soft ball is thrown with swing on a vertical circle with a force, the final velocity is calculated.
