A horizontal force of magnitude 39.5 N pushes a block of mass 4.05 kg a distance of 3.00 m across a floor, where the coefficient of kinetic friction is 0.600. (a) How much work is done by that applied force on the block-floor system? (b) During that displacement, the thermal energy of the block increases by 44.0 J. What is the increase in thermal energy of the floor? (c) What is the increase in the kinetic energy of the block?

A block of mass m = 5.00 kg is pushed a distance d = 3.00 m along a frictionless, horizontal table by a constant applied force of magnitude F = 20.0 N directed at an angle theta = 37.0 degree below the horizontal as shown in Figure. 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.

Correct is given, please explain why for each Concept Question 4 – An object is initially at rest. A net force (which always points in the same direction) is applied to the object so that the power supplied by the net force is constant. As the object gains speed, a) the magnitude of the net force decreases. b) the magnitude of the net force increases. c) the magnitude of the net force remains constant. d) the magnitude of the net...
