Seventh Edition Vector Mechanics for Engineers: Dynamics Sample Problem 12.1 SOLUTION: ⢠Resolve the equation of motion for the block into two rectangular component equations. A 200-lb block rests on a horizontal plane. Find the magnitude of the force P required to give the block an acceleration or 10 ft/s2 to the right. The coefficient of kinetic friction between the block and plane is mk ï½ 0.25. ⢠Unknowns consist of the applied force P and the normal reaction N from the plane. The two equations may be solved for these unknowns. 12 - 30
