Question

A sled slides down a snow-covered hill at CONSTANT SPEED. If the hill makes an ANGLE of 10degrees ABOVE THE HORIZONTAL, WHAT IS THE COEFFICIENT OF KINETIC FRICTION BETWEEN THE SLED AND THE SNOW?

Well, constant speed means no net force, so friction must equal the component of weight down the hill

mg*mu*cosTheta=mg*SinTheta

TanTheta=mu
check my thinking.
0.176
Coefficient of kinetic friction=
tan0- Accelaration/gcos0
