"When a person walks on a rough surface the frictional force exerted by the surface on the person is opposite to the direction of his motion". Is it true or false ?

A block of mass 2 kg is pushed against a rough vertical wall with a force is 40 N. Coefficient of static friction being 0.5. Another horizontal force is 15 N, is applied on the block in a direction parallel to the wall. Will the block move? If yes in which direction? If no, find the frictional force exerted by the wall on the block.
