Problem
A box of mass m is given an initial speed v and slides along a horizontal surface. The coefficient of kinetic friction between the box and the surface is μ. The box stops after sliding a distance d. The stopping distance, d, would be doubled if which of the following quantities were doubled?
a. only the mass of the box.
b. only the initial speed of the box.
c. only the coefficient of friction between the box and the surface.
d. only the mass of the box and the coefficient of friction between the box and the surface.
e. only the initial speed of the box and the coefficient of friction between the box and the surface.
