To push a piece of heavy furniture across the carpet usually takes more force to get it moving than it takes to keep it moving, this is because:

a) it does not take more force
b) the kinetic coefficient of friction is larger than the static coefficient
c) of Newton’s Third Law
d) the static coefficient of friction is larger than the kinetic coefficient
