If a car generates 22 hp when traveling at a steady 100 km/h , what must be the average force exerted on the car due to friction and air resistance

The average force exerted on the car is 590.12 N.

Explanation:

Given that,

The power generated, P = 22 hp = 16405.4 W

Speed of the car, v = 100 km/h = 27.8 m/s

We need to find the average force exerted on the car due to friction and air resistance.

We know that,

Power, P = F v

Where

F is force exerted on the car

So, the average force exerted on the car is 590.12 N.

c)as speed changes, wavelength and frequency change.
