A vehicle manufacturer is considering an engine for a new sedan (CD = 0.3, Af = 21 ft2). The desired maximum speed is 100 mi/h at sea level (? = 0.002378 slugs/ft3). However, the designer selected an underpowered engine of light weight (the car with the engine weigh 2100 lb) that achieved a maximum speed of 90 mi/h. Determine the required engine power and the final weight of the car if it is to achieve 100 mi/h speed, assuming that 2 lb of additional engine weight is added for each horsepower of additional engine power..
