Problem 5-102 Friction force - C

A skier of mass $79\; kg$ is sliding at constant velocity down a slope inclined at $8.3^\circ$ to the horizontal. Determine the magnitudes of:

(a) the normal force exerted on the skier.
(b) the frictional force exerted on the skier.

No. The normal force acts normal (perpendicularly) to the plane.

Try again.
