## Homework Statement

A 2.0 kg mass rests on a frictionless wedge that has an acceleration of 15 m/s2 to the right. The mass remains stationary relative to the wedge, moving neither higher nor lower. (a) What is the angle of inclination, θ, of the wedge? (b) What is the magnitude of the normal force exerted on the mass by the incline? (c) What would happen if the wedge were given a greater acceleration?

## Homework Equations

trig identities

## The Attempt at a Solution

I just can't get my mind around this one to get started. I am unsure how to interpret the acceleration of the box since it has no additional acceleration other than that of the wedge.

I believe the second part will be something akin to Fn=mgsintheta...

And if the wedge accelerated more the box would probably move up the wedge.
