A new sport car has a drag coefficient of 0.29 and a frontal area of 20ft^2, and is traveling at 100 mi/h.
How much power is required to overcome aerodynamic drag if p = 0,0002378 slugs/ft^3?
Please help me with the steps as well. I really need help
Thank you so much guys.

Aerodynamic drag is
D = 1/2 rho A V^2 Cd
Where rho is density (it looks a bit like a 'p'...), A is the area, V is the speed, and Cd the drag coefficient.
This returns a drag of 14.8345 pounds.
Power is force times a speed. So this means 3.9559 hp of power is needed to overcome the aerodynamic drag..
