Continue the analysis of Problem 60 in Chapter 19. Following a collision between a large spacecraft and an asteroid, a copper disk of radius 28.0 m and thickness 1.20 m, at a temperature of 850°C, is floating in space, rotating about its axis with an angular speed of 25.0 rad/s. As the disk radiates infra red light, its temperature falls to 20.0°C. No external torque acts on the disk.
(a) Find the change in kinetic energy of the disk.
(b) Find the change in internal energy of the disk. (b) Find the amount of energy it radiates.
