A dock worker pushes a m = 2.20 kg block a distance

A dock worker pushes a m = 2.20 kg block a distance d = 3.00 m along the floor by a constant force of magnitude F = 16.0 N directed at an angle 0 = 21.0 below the horizontal as shown in the figure. Assume the floor is frictionless. (Enter your answers in joules.) m (a) Determine the work done on the block by the applied force (the force on the block exerted by the dock worker). J (b) Determine the work done on the block by the normal force exerted by the floor. J (c) Determine the work done on the block by the gravitational force. (d) Determine the work done by the net force on the block. J
