How large must this force be

Reference no: EM13508183

You are holding a bulletin board weighing 9.10 N in place against a wall while your friend secures it to the wall. To keep it from slipping, you apply a force perpendicular to the bulletin board, pressing it directly into the wall. How large must this force be if the coefficient of static friction with the wall is 0.39?
