a bed is pulled across a perfectly horizontal floor. The person pulling the bed pulls with a constant force of 500N at an angle of 35 degrees above the horizontal. A frictional force of 40N is acting on the bed as it accelerates across the floor. The bed has a mass of 30kg and does not accelerate vertically, remaining in contact with the floor.

A. Calculate the normal force exerted by the floor on the bed

B. Calculate the acceleration of the bed
