6) A force Fis exerted on a 5 kg block to move it across a rough surface, as 1 point
shown. The magnitude of the force is initially 5 N, and the block moves at a
constant velocity. While the block is moving the force is instantaneously
increased to 12 N. How much kinetic energy does the block now gain as it
moves a distance of 2 m?*
