A child wearing socks is trying to see how far he can slide across his kitchen floor. If he has a mass of 48 kg and the coefficient of friction between him and the floor is
0.51, how far can he slide with an initial velocity of 7.8 m/s?

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.
