A sled and its rider are moving at a speed of 40 ms along a, Ask an Expert

Academics

A sled and its rider are moving at a speed of 4.0 m/s along a horizontal stretch of snow. The snow exerts a kinetic frictional force on the run ner of the sled, so the sled slows down and eventually comes to a stop. The coefficient of kinetic friction is 0.050. what is the displacement of the sled?
