The car shown in Fig. below has a mass of $2\mathrm{Mg}$ and a center of mass at $\mathrm{G}$. Determine the acceleration if the rear "driving" wheels are always slipping, whereas the front wheels are free to rotate. Neglect the mass of the wheels. The coefficient of kinetic friction between the wheels and the road is ${\mu }_k=0.25$
