Problem 5-102 Friction force - Part 7 - A
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
\(a_x = a_y = 0 \\ mg \sin \theta - F_f = 0 \\ F_f = 1.1\times10^2\; N \; \text{ (answer to part (b))}\)
No. The two forces point in opposite directions and you have the wrong component of \(mg\).
