When a pitcher throws a curve ball, the ball is given a fairly rapid spin.
Part A If a 0.15 kilogram baseball with a radius of 3.7 centimeter is thrown with a linear speed of 42 m/s and an angular speed of 44 rad/s, find how much of its kinetic energy is translational energy? Suppose the ball is a uniform, solid sphere.
(J)
Part B Determine how much of its kinetic energy is rotational energy?
