Question

Somewhat surprisingly, your physics skills land you a position on the competitive shuffleboard team. You release a disk (mass 0.425 kg ) with speed 1.71 m/s, and it eventually stops due to friction. The coefficient of kinetic friction between the disk and the waxed surface is 0.100.

What is the work done by friction bringing the disk to a stop?

What is the average thermal power emitted by the disk as it stops?
