A block of mass m = kg is pushed a distance d = m along a frictionless, horizontal table by a constant applied force of magnitude F = N directed at an angle θ = ° below the horizontal as shown in Figure P7.5. Determine the work done on the block by (a) the applied force, (b) the normal force exerted by the table, (c) the gravitational force, and (d) the net force on the block.
