11 (20 pts) A 5.0 kg block is pushed along the floor by a force that makes a 30° angle below the horizontal. There is friction between the floor and the block a Pushing force 30 m a) Draw a free-body diagram showing all the forces acting on the block. b) Write equations of motion of the form EF = ma for the horizontal components and the vertical components of all the forces. Do not use numbers and do not solve the equations c) If the pushing force is 40 Newtons, what is the magnitude of the normal force on the block? Kitic d) if the coefficient of static friction, f. = 0.4, what is the acceleration of the block?
