Hello, here is the problem I've been stuck on. It seems simple but I am getting the wrong answer. Any help would be appreciated.
A 20.0-kg rock is sliding on a rough, horizontal surface at 8.00 m/s and eventually stops due to friction. The coefficient of kinetic friction between the rock and the surface is 0.200.
What average thermal power is produced as the rock stops?
My answers thus far are
784
1040
427
They were all wrong.
