a block of mass m = 2.50 kg is pushed a distance of d = 2.20 m along a frictionless horizontal table by a constant applied force of magnitude F = 16.0 N directed at an angle of 25.0 degrees below the horizontal. Determine the work done by
(a) the applied force,
(b) the normal force exerted by the table,
(c) the force of gravity, and
(d) the net force on the block.
