An object slides on a level floor. It slows and comes to a stop with a constant acceleration of magnitude $2.4\mathrm{m}/{\mathrm{s}}^2$. What is the coefficient of kinetic friction between the object and the floor? 0.24 0.12 0.48 It is impossible to determine without knowing the mass of the object.
