Homework Statement
This is a 2 part question.
A block of mass m rests on a frictionless wedge that has an inclination of theta and mass M.
a) Find the acceleration of the wedge M to the right such that the block m remains stationary relative to the wedge.
c) You now find out that a force of magnitude F was exerted (say, by somebody's hand) on the wedge as shown in the picture below. What is the magnitude F for which the block m remains stationary relative to the wedge? Use m, M, g, and theta.
Homework Equations
F=ma
The Attempt at a Solution
I drew a FBD but I can't fathom how acceleration in the horizontal will cause a block not to move in the vertical.
