A 750-g disk sliding along frictionless ice with a speed of 8.5m/s strikes a stationary rod-disk combo 12-cm from itscenter-of-mass. This rod-disk combo is made from a 360-g rod thatis 35-cm long, with 2 150-g solid disks of radius 7.0-cm attached,one on each end of the rod. After the perfectly elastic collision,the disk moves off along a path that is 28Ă‚Âş above its originalpath, while the rod-disk combo spins about its center-of-mass as itmoves off at an angle as well. Using this information, find thetranslational speed of both objects after the collision, theangular speed of the rod-disk combo, and the angle of itstrajectory.
