Consider a 1,492 kg car cruising at constant speed of 59 km/h. Now the car starts to pass another car, by accelerating to 124 km/h in 9 s. Neglect air drag and friction and assume the road is level. By taking the entire car as the system and applying an energy balance, determine the additional power (kW) needed to achieve this acceleration to 1 decimal place. (note: 1 m/s = 3.6 km/h).
