F A force of F = 67.2 N pushes a block with a mass m = 5.46 kg along a horizontal surface at a constant speed of U = 1.44 m/s. Part 1) What is the kinetic energy of the block? Part2) As the block moves through a distance of d = 3.26 In, how much work is done by the force F on the block? W = J Part 3) Which of the following statements are true? C] The block is doing work against the frictional force (i.e., the work done by the frictional force is negative). C] The block is doing work against the gravitational force (i.e., the work done by the gravitational force is negative). C] As the speed of the block does not change, the net work done on the block is zero. C] There is no frictional force in this case
