What? do you have a question??
When a car maintains a velocity of exactly 65 mph, it's acceleration is zero.
<h3>What is acceleration?</h3>
The acceleration is time rate of change of velocity.
When the velocity is not changing with respect to time, it is said to be an object moving with constant velocity.
At constant velocity, there is no acceleration.
Thus, when a car maintains a velocity of exactly 65 mph, it's acceleration is zero.

Answer:
(b) Friction increases as the normal force (weight) increases, and also depends on the surface
Explanation:
The coefficient of friction relates the normal force between surfaces to the friction force opposing motion. The coefficient depends on the surface.
The appropriate choice is ...
Friction increases as the normal force (weight) increases, and also depends on the surface
