A bola consists of three massive, identical spheres conected to a common point by identical lengths of sturdy string (Fig. 11-51a). To launch this native South American weapon, you hold one of the spheres overhead and then rotate that hand about its wrist so as to rotate the other two spheres in a horizontal path about the hand. Once you manage sufficient rotation, you cast the weapon at a target. Initially the bola rotates around the previously held sphere at angular speed i but then quickly changes so that the spheres rotate around the commonconnection point at angular speed f (Fig. 11-51b). (a) What is the ratio f /i? (b) What is the ratio Kf /Ki of the corresponding rotational kinetic energies? Li=Lf 3. The attempt at a solution - I'm absolutely stumped on this problem. Mainly because I'm given no numbers and don't know how to get a ratio with just the equations. Where would I begin on a problem like this?
