A 15-kg block is pushed across a rough horizontal surface by a force that is angled 30.0◦ below the horizontal. The magnitude of the force is 100 N and the acceleration of the block as it is pushed is 4 m/s2. What is the magnitude of the contact force (the vector addition of normal force and friction) exerted on the block by the surface?
