The truck shown in Figure I has a mass and a center

The truck shown in Figure I has a mass and a center of mass at G. (a) Determine the shortest time possible for the rear-wheel drive, 2-Mg truck to achieve a speed of 16 m/s with a constant acceleration starting from rest. The coefficient of static friction between the wheels and the road surface is , = 0.8. The front wheels are free to roll. (10 Marks) (b) If the driver needs to increase the speed achieved in (a) by 5%, redesign the dimension of the car in order to achieve the new targeted acceleration. Justify your answer with calculation. (10 Marks) Go75 m -1.5 m- Figure 1
