A girl coasts down a hill on a sled, reaching level ground at the bottom with a speed of 6.7 m/s. The coefficient of kinetic friction between the sledís runners and the hard, icy snow is 0.048, and the girl and sled together
weigh 615N. The acceleration of gravity is 9.81m/s2.How far does the sled travel on the level ground before coming to a rest? Answer in units of m I have gotten 2 answers by myself. 6.9 and 29.52. If you could give me what you got it would be greatly appreciated.
