Homework Help: physics

Posted by Jessica on Thursday, July 12, 2012 at 1:37pm.

There are two spinning disks A and B arranged so that they initially are separated but can be pushed into contact. Disk A is made of a lighter material, so it has a moment of inertia that is one third that of disk B. Disk A starts off spinning at some i when the two disks are separated. The two disks are then pushed together, coupling their motion. 2400 J of heat energy were produced in this process. What was the initial kinetic energy of disk A?
