Question:

The drag force on a car is given by

where ρ is the density of air (1.23 kg ∕ m3), v is the velocity in units of m ∕ s, A is the projected area of the car (2.5 m2), and CD is the drag coefficient (0.2). The amount of power in watts required to overcome such drag force is P = FDv, and the equivalent horsepower required is Hp = P ∕ 746. Write a program that accepts a car’s velocity and computes the power in watts and in horsepower needed to overcome the resulting drag force. Note: 1 mph = 0.447 m ∕ s.
