Problem 5-102 Friction force - Part 2 - B

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

Correct.

While there is no incorrect orthogonal coordinate system this one is the most convenient.

Read the problem carefully and then choose the correct statement below.

(A)   In the chosen coordinate system there is acceleration in the \(x\) direction but not in the \(y\) direction.

(B)   In the chosen coordinate system there is acceleration in the \(y\) direction but not in the \(x\) direction.

(C)   In the chosen coordinate system there is acceleration in both the \(x\) direction and the \(y\) direction.

(D)   In the chosen coordinate system there is no acceleration in any \(x\) direction.
