Question

A 20 kg mass slides down an inclined plane which is at an angle of 60 degrees to the horizontal

1. Horizontal component of weight force
2. Vertical component of weight force
3. Angle
4. Normal force
5. Net fx
6. Acceleration along incline

I really do not get how to do this, I don't even know where to start

Answer 1

First we must assume no friction or we can't go anywhere. Draw a FBD, do a little geometry and here we go.
1) There is none, weight is down
2) 20(9.8)
3) Ummm. You said it was 60
4)Fn = mg cos60
5) Fnet = mg sin60
6) Fnet = ma so a = g sin60
