Problem: The mass of a car is 1500 kg. The shape of the car's body is such that its aerodynamic drag coefficient is D = 0.390 and frontal area is 2.50 m2. Assuming that the drag force is proportional to v2 and ignoring other sources of friction,
A. Calculate the power required to maintain a speed of 100 km/h as the car climbs a long hill sloping at 3.50°.
Solve the above problem and I want you to explain the physics in this problem.
