Homework Statement
A block of mass M is on a plane with an incline of Theta. What horizontal force must the ramp be pushed so that the block does not move relative to the ramp.
This is to be solved generally.
Homework Equations
Force of gravity on block: m*g*sin(theta)
Normal force: -m*g*cos(theta)
The Attempt at a Solution
I have no idea where I should start.
I the normal force needs to counteract the force of gravity on the block, but I don't know how the horizontal force on the ramp factors into the normal force.
