Question

Use an impulse of torque and conservation laws to calculate the right location along a baseball bat to contact the ball when swinging. If you grip the handle of the bat a distance b away from the center of mass, you're trying to find how far b' on the other side of the center of mass you should make contact with the ball. The physics is more complicated if your swinging the bat, but this calculation is easiest if you assume that the bat is stationary and the ball hits the bat with some initial momentum mv₀ perpendicular to the bat, and it rebounds back along the same line. This location is sometimes called the ``center of percussion,'' and it is related to the ``center of oscillation'' of a Kater's pendulum.
