A girl coasts down a hill on a sled, reaching
level ground at the bottom with a speed of
7.0 m/s. The coefficient of kinetic friction
between the sled’s runners and the hard, icy
snow is 0.054, and the girl and sled together
weigh 749 N.
The acceleration of gravity is 9.81 m/s

.
How far does the sled travel on the level
ground before coming to a rest?
