Question

You are driving on the highway, and you come to a steep downhill section. As you roll down the hill, you take your foot off the gas pedal. You can ignore friction, but you can't ignore air resistance.

Answer 1

Weight of the car, normal force, drag force

Step-by-step explanation:

The forces acting on the car are:

• The normal force which acts perpendicularly to the downhill plane
• The weight of the car which acts vertically downwards
• The drag force due to air resistance which acts in opposition to the motion of the car

Friction is ignored, so the force due to friction is assumed negligible
