**Problem Statement:**
The sports car shown in Figure 1 has been designed such that the 260-kg engine \(E\) and 165-kg transmission \(T\) have been placed over the front and rear wheels, respectively. Their mass centers are located at \(G_E\) and \(G_T\). The mass center of the remaining 512-kg body and frame is located at \(G_b\).
**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 \(\mu_s = 0.56\). Neglect the mass of the wheels and driver.
Express your answer to three significant figures and include the appropriate units.

**Figure Description:**
The diagram consists of a yellow sports car with measurements and labels indicating the positions of the car's mass centers:
- The distance from the front of the car to \(G_E\) is 0.5 m.
- The distance from the front wheels to \(G_b\) is 1.25 m.
- The distance from the front wheels to the rear wheels is 1.70 m.
- The distance from \(G_T\) to the rear is 0.40 m.
