1. The problem statement, all variables and given/known data A block of mass 2 kg is pushed against a rough vertical wall with a force of 40N , co-efficient of static friction being 0.5.Another horizontal force of 15N is applied on the block in the direction parallel to the wall. 2. Relevant equations Will the block move? If yes, in which direction? If no, find the frictional force exerted by the wall on the block 3. The attempt at a solution The first thing which puzzles me about this problem is that in which direction should the parallel force be acting? I think the block will move;but do we take into consideration the gravitational force acting downwards?
