Problem 1: A 2.80kg block is placed on a rough (us=0.540) incline that makes an angle of 52.0° with respect to the horizontal. A pushing force horizontal to the ground is applied to the top of the block (This would make the force have an angle of 52.0° below the surface of the inclined plane, up the plane) to make the block stationary on the plane. What is the minimum pushing force needed to keep the block stationary on the plane? (10 points)
