Air drag is the frictional force which is due to air molecules and it is always opposite to the direction of motion
So here direction of air resistance is always opposite to the motion or velocity
Now if Car is travelling then the force on the car due to engine is always in the direction of velocity of car
Because here engine will provide the force to accelerate the car.
So opposite to that motion there is air resistance.
So here correct answer will be
<em>B) The forward force applied by the engine</em>
Answer:
so, why we have to find here..

Inertia I think because I've heard it around school and in science
An advertisement for an all-terrain vehicle (ATV) claims that the ATV can climb inclined slopes of 35°. The minimum coefficient of static friction needed for this claim to be possible is 0.7
In an inclined plane, the coefficient of static friction is the angle at which an object slide over another.
As the angle rises, the gravitational force component surpasses the static friction force, as such, the object begins to slide.
Using the Newton second law;




N = mg cos θ
Equating both force component together, we have:



From trigonometry rule:

∴



Therefore, we can conclude that the minimum coefficient of static friction needed for this claim to be possible is 0.7
