A sled is given a push across a horizontal surface. The sled has a mass m, the push gives it an initial speed of 2.80 m/s, and the

coefficient of kinetic friction between the sled and the surface is 0.115.

(a) Use energy considerations to find the distance (in m) the sled moves before it stops.

(b) What If? Determine the stopping distance (in m) for the sled if its initial speed is doubled to 5.60 m/s.
