Answer to Question #239483 in Physics for rshiii

Question

7. A skier with a mass of 62 kg is sliding down a snowy slope. Find the coefficient of kinetic friction for the skier if friction is known to be 45.0 N

Answer 1

The force friction is

$$f=\mu mg\sin\theta,\\\space\\ \mu=\frac{f}{mg\sin\theta}=\frac{0.0741}{\sin\theta},$$

where theta is the angle of the slope.
