Question

Suppose you have a car traveling down the road at constant speed and not changing direction. It is experiencing gravity, wind resistance and frictional forces from the road. What can be said about the car’s acceleration?

Answer 1

zero

Step-by-step explanation:

As the speed is constant and the direction is not changing then we can say that the acceleration of the car is zero.

Acceleration is defined as the rate of change of velocity.

As the speed is constant so the magnitude of velocity is constant and the direction remains same so the direction of velocity remains same. it means the velocity if constant. And hence the acceleration is zero.
