Find the magnitude, Fww, of the force that the wall exerts on the wedge

Question

A wedge with an inclination of angle theta rests next to a wall. A block of mass m is sliding down the plane, as shown. There is no friction between the wedge and the block or between the wedge and the horizontal surface.

Express Fww in terms of theta and m, along with any necessary constants.

Answer 1

Fww = g * m * tan(theta)
