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?

Power = 11.81[hp]

Explanation:

We remember that the power is equal to the product of speed by force, in this way we have:

P = F * V

where:

F = force [N]

V = velocity [m/s]

we must consider the following relationship

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
