The car shown has a mass of m = 1 4 0 0 = 1 4 0
Question:
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=0.250. The dimensions are a=1.15 m, b=1.65 m, and c=0.250 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=84.0 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=84.0 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=84.0 km/h , starting from rest, if the engine drives all four wheels.
