1. The problem statement, all variables and given/known data 2. Relevant equations F=MA 3. The attempt at a solution Weight M*G=55.5*9.81 Parallel force sin(30)544.455=272.228 Perpendicular force To Plane cos(30)544.455=471.512 Figured out that the man is pushing with a force of tan(30)544.455=314.341N Normal Force Wouldn't it be the opposite to the perpendicular force? 471.512? But this is wrong??? HELP. What other force in the perpendicular direction am I missing?
