Answer to Question #294563 in Physics for sam

Question

A 10-kg crate i s at rest on a surface i nclined at a 45-degree angle. Suppose

that the static friction coefficient between the crate and the inclined surface is 0.50.

Answer 1

Find the angle at which the crate will start slipping:

$$\theta_s=\arctan\mu_s=26.6°.$$

The box will slide down.
