The car shown has a mass of m = 1 4 0 0 = 1 4 0

The car shown has a mass of m$=1400$ kg and a center of mass located at G$.$ The coefficient of static friction between the wheels and the road is mu s$=0\mathrm{.}250.$ The dimensions are a$=1\mathrm{.}15$ m$,$ b$=1\mathrm{.}65$ m$,$ and c$=0\mathrm{.}250$ m$.$ Assume the car starts from rest, the wheels do not slip on the road, and that the car experiences constant acceleration. Neglect the mass of the wheels.

Part A$)$ Determine the shortest time it takes the car to reach a speed of v$=84\mathrm{.}0$  km$/$h $,$ starting from rest, if the engine drives only the rear wheels.

Part B$)$ Determine the shortest time it takes the car to reach a speed of v$=84\mathrm{.}0$ km$/$h $,$ starting from rest, if the engine drives only the front wheels.

Part C$)$ Determine the shortest time it takes the car to reach a speed of v$=84\mathrm{.}0$  km$/$h $,$ starting from rest, if the engine drives all four wheels.
