A 75.0 kg object is on an incline of 30 degrees horizontally.
I have to calculate several things from this, and I need help with some of them.
I have to find the following:
1. Static coefficient of friction
2. Kinetic coefficient of friction
3. Gravitational force
4. Normal force
5. Applied force
I am not sure how to calculate 1, 2, or 5, but I have 2 and 3 done.
Fg = -9.81 * 75.0
Fg = -735.75 N (This is number 3)
Fn = 9.81 * 75 * cos(30)
Fn = 637.18 N (This is number 4)
Any help is appreciated with the other questions! Thanks.

Is it barely not moving, is it moving at constant velocity, is it accelerating?
I am supposed to figure out if the box is moving later on in the problem set. The crate and the ramp are both wooden though. My book says the static coefficient of wood on wood is 0.4 and the kinetic coefficient of wood on wood is 0.2.
