A man pushes a m = 3.40 kg block a distance d = 6.60 m along the floor by a constant force of magnitude F = 16.0 N directed at an angle 8 = 26.0 below the horizontal as shown in the figure. Assume the floor is frictionless, (Enter your answers in joules.) (a) Determine the work done on the block by the applied force the force on the block exerted by the man). 12 (b) Determine the work done on the block by the normal force exerted by the floor 11 (0) Determine the work done on the block by the gravitational force. (d) Determine the work done by the net force on the block.
