The formula for finding the horsepower of a vehicle is: Horsepower = weight × ( velocity 234 ) 3 Weight is the total weight of t
he vehicle, driver and any passengers. Velocity is determined by the speed at the end of a quarter mile run. The newest hybrid auto weighs 2200 pounds and the driver is 180 pounds. At the end of the quarter mile run, the speed is 98 miles per hour. What is the horsepower of the car rounded to the nearest whole number?
The answer is option 2 Power = 175 hp The correct formula to calculate the power is: Power = weight * (speed / 234) ³ Where the weight is that of the vehicle plus the driver's Therefore the calculation is as follows: Power = (2200 + 180) * (98/234) ³ Power = 174.8266 hp Rounding ... Power = 175 hp
