When we drive our car at 100 feet per second [ft/s], we measure an aerodynamic force (called drag) of 65 pounds-force [lb Subscript f ] that opposes the motion of the car. How much horsepower [hp] is required to overcome this drag?
Answers: 3
![1 [hp] = 550 [lbf*\frac{ft}{s}]\\therefore:\\(65*100) = P\\P = 6500 [lbf*\frac{ft}{s} ]\\1[hp] = 550 [lbf*\frac{ft}{s} ]\\x = 6500 [lbf*\frac{ft}{s} ]\\x = 11.8 [hp]](/tpl/images/0525/2602/4caf1.png)
