Question:

A block of mass $2 \mathrm{~kg}$ is pushed against a rough vertical wall with a force of $40 \mathrm{~N}$, coefficient of static friction being $0.5$. Another horizontal force of $15 \mathrm{~N}$, 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.
