A 5 kg solid cylinder is at rest on a Vblock that is incline

A 5 kg solid cylinder is at rest on a V-block that is inclined 30o to the horizontal as shown in the diagram.

(a) Determine the frictional force acting on the cylinder at each side whilst at rest.

(b) Find the value of the push force, parallel to the axis of the cylinder, required to allow the cylinder to start to move up the incline, if the coefficient of friction between the cylinder and the V-block is 0.40.
