Question

Part A - Shortest Time to Reach a Glven Speed with Rear-Wheel Drive Learning Goal: To use the equations of motion as they relate to linear translation of an abject to determine characteristics about its motion. 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 Mix - 0.230. The dimensions aro u – 1.05 m, b= 1.75 m, and c = 0.350 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 (Figure 1) Determine the shortest time it takes the car to reach a speed of 1 = 76.0 km/h, starting from rest, if the engine drives only the rear wheels. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) HA o ?
