The sports car shown in (Figure 1) has been designed so that the 260-kg engine E and 165-kg transmission I have been placed over the front and rear wheels, respectively. Their mass centers are located at Gg and Gr. The mass center of the remaining 512-kg body and frame is located at G Part A If power is supplied to the rear wheels only, determine the shortest time it takes for the car to reach a speed of 80 km/h, starting from rest. The front wheels are free rolling, and the coefficient of static friction between the powered wheels and the road is = 0.56. Neglect the mass of the wheels and driver.
