A man pushes a m = 2.20 kg crate a distance d = 2.40 m along the floor by a constant force of magnitude F = 16.0 N directed at an angle 0 = 20.0 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 crate by the applied force (the force on the crate exerted by the man). J (b) Determine the work done on the crate by the normal force exerted by the floor. J (c) Determine the work done on the crate by the gravitational force. J (d) Determine the work done by the net force on the crate.
