Question

The crate is at rest on the incline. What can you say about the force of friction acting on the crate?A. the frictional force points up the inclineB. the frictional force points down the inclineC. the frictional force is zero

Answer 1

Answer:

The frictional force points up the incline.

Explanation:

It is given that, the crate is at rest on the incline.  We know that the forces acting on the crate are force of gravity, normal and the force of friction. We know that the frictional force is the force that opposes the motion of an object.

In this case the crate is at rest. The crate will have static friction, that points up the incline.

So, the correct option is (A) "the frictional force points up the incline".
