A child sets a 2.5 kg block in motion by giving it a push along a floor. This gives the block a velocity of 3.2 m/s. 1. What is the net work done on the block (when the velocity reaches 3.2 m/s)? 2. Now, the child releases his/her hands. How far will the block slide before coming to rest, if the coefficient of kinetic friction between the block and the floor is 0.32?
