A girl coasts down a hill on a sled, reaching level ground at the bottom with a speed of 6.6 m/s. The coefficient of kinetic friction between the sled's runners and the hard, icy snow is 0.047, and the girl and sled together weigh 755 N.
The acceleration of gravity is 9.81 m/s^2.
How far does the sled travel on the level ground before coming to a rest?
Answer in units of m.
