A box is given a push across a horizontal surface. The box has a mass m, the push gives it an initial speed of 3.40 m/s, and the coefficient of kinetic friction between the box and the surface is 0.110.  Use energy considerations to find the distance (in m) the box moves before it stops.   What If? Determine the stopping distance (in m) for the box if its initial speed is doubled to 6.80 m/s.
