A 27.0kg sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 71.0N and is directed at an angle of 30.0deg above the horizontal. Determine the coefficient of kinetic friction.

Answer 1

Friction = (71.0N * sin(30.0deg)) / (27.0kg * 9.8m/s^2)

Friction = 0.25
