Angular Collisions How much thermal energy is created in the process of disk 1 falling on disk 2 such that they reach a common final angular velocity? You do not need to worry about the gravitational potential energy because the initial separation of the disks is small.

Activity 3 - Practice Problems Solve the following problems with complete solutions. 1. The giant sequoia General Sherman in California has a mass of about 2.00 6 10° kg, making it the most massive tree in the world. Its height of 83.0 m is also impressive. Imagine a uniform bar with the same mass and length as the tree. If this bar is rotated about an axis that is perpendicular to and passes through the bar's midpoint, how large an angular acceleration would result from a torque of 4.60 10' N•m? (Note: Assume the bar is thin.) 2. A 43.0 kg wheel, essentially a thin hoop of radius 1.50 m, is rotating at 380 revs/min. It must be brought smoothly to a stop in 20.0 s.
