## Homework Statement

The weight of a book sliding down a frictionless inclined plane can be broken into two vector components: one acting parallel to the plane, and the other acting perpendicular to the plane.

(a) At what angle is the components equal?

(b) At what angle is the component parallel to the plane equal to zero?

(c) At what angle is the component parallel to the plane equal to the weight?

## Homework Equations

Fnet = ma

## The Attempt at a Solution

I'm not really sure how to approach this.

My guess for (a) is 45 just because it sounds reasonable that the components would be equal at the middle of 0 to 90 degrees.
