Solve the problem in the Mini-Example on p. 552 using momentum methods and the concept of impulsive force. Specifically, consider a ball hitting a bat at a distance d from the handle when the batter has “choked up” a distance δ. Find the “sweet spot” P (more properly called the center of percussion*) of the bat B by determining the distance d at which the ball should be hit so that the lateral force (i.e., perpendicular to the bat) at O is zero. Assume that the bat is pinned at O,it has mass m, the mass center is at G, and the mass moment of inertia is IG.
