Problem 5-102 Friction force - Part 4 - 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.

Accumulated Solution

FBD of skier

FBD

\(a_x = a_y = 0 \\ mg \sin \theta - F_f\)

Correct.

These forces add up to:

(A)   \(0\)

(B)   \(mg\)

(C)  \(F_N  -  mg \cos \theta\)
