Asked by Harold
A 10 kg sled slides down a hill with an incline of 30 degrees above the horizontal. Because of friction, it maintains a constant speed. For every meter that is traveled, how much energy (in joules) does the sled lose?
I say 98 sin(30) Joules?

If you mean how much kinetic and potential energy, you only lose potential energy, and that loss equals M g sin 30, which is what you came up with.
