A 150-N sled is pulled up a 28 $\degree$ slope at a constant speed by a force of 120 N. What is the coefficient of kinetic friction between sled and slope?
A) 0.53
B) 0.22
C) 0.37
D) 0.33

Question

Quizplus · Accepted Answer

The force of friction is equal to the force parallel to the slope minus the pulling force. The normal force is the component of the weight perpendicular to the slope. The coefficient of kinetic friction is the force of friction divided by the normal force.
