A box is given a push across a horizontal surface. The box has a mass m, the push gives it an initial speed of vi, and the coefficient of kinetic friction between the box and the surface is μk. (a) Use energy considerations to find an expression for the distance the box moves before it stops. (Use any variable or symbol stated above along with the following as necessary: g.) d = (b) What If? If the initial speed of the box is increased by a factor of 3.5, determine an expression for the new distance dnew the box slides in terms of the old distance d. d
