The car shown has a mass of m=1000 kg and a center of mass

located at G. The coefficient of static friction between the wheels

and the road is μs=0.250.

The dimensions are **a=1.15 m**, **b=1.55
m**, and

**c=0.290 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 – Shortest Time to Reach a Given Speed with Rear-Wheel

Drive

Determine the shortest time it takes the car to reach a speed of

v=88.0 km/h , starting from rest, if the engine drives only the

rear wheels.

Part B – Shortest Time to Reach a Given Speed with Front-Wheel

Drive

Determine the shortest time it takes the car to reach a speed of

v=88.0 km/h, starting from rest, if the engine drives only the

front wheels.

Part C – Shortest Time to Reach a Given Speed with All-Wheel

Drive

Determine the shortest time it takes the car to reach a speed of

v=88.0 km/h, starting from rest, if the engine drives all four

wheels.
