A Giant Frisbee. A solid copper disk of radius 10.50 m is launched toward the sun like a gigantic Frisbee with a constant linear velocity of 350 m/s and a rotation rate of exactly 438.7 rpm about its central axis. At the time of launch, the disk was very cold (-191.1 °C). As it approaches the sun, however, it will get very hot. You and your team have been brought in to determine whether the increased temperature will affect the motion of the disk. (a) Will the rate of rotation be affected when the disk becomes hot? If so, how and why? (b) What will be the rate of rotation (in rad/s) when the copper disk reaches a temperature of 785.9 °C? There are no external torques acting on the disk. S
