A girl coasts down a hill on a sled, reaching
a level surface at the bottom with a speed
of 7.4 m/s. The coefficient of kinetic friction
between runners and snow is 0.044, and the
girl and sled together weigh 761 N.
The acceleration of gravity is 9.8 m/s².
How far does the sled travel on the level
surface before coming to a rest?
Answer in units of m.
