Question

An object is at rest on an incline. The component of gravity acting downward and along the incline on the object is described as Fg, x = +8.0 N. Which axis is pointing up the incline?

1) X-axis
2) Y-axis
3) Z-axis
4) Cannot be determined

Answer 1

The y-axis is pointing up the incline.

Step-by-step explanation:

The component of gravity acting downward and along the incline on the object is Fg, x = +8.0 N. When an object rests on an incline, the force parallel to the incline is the component of gravity acting along the incline. In this case, the component of gravity is directed downward and along the incline, so the y-axis is pointing up the incline.
