Question

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.
