A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?

It's not possible. Acceleration is defined as a change in velocity, so if the speed is constant, the acceleration is zero. If the acceleration is zero, so is the net force.

If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
What is contant acceleration?
motion of a body with constant acceleration, that means it has equal velocity in equal intervals if time.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
Can a body moving at constant speed have a non-zero accelertion?
Constant speed means constant velocity. Constant velocity means an object is covering same distance in equal intervals of time. So how is it possible to have acceleration. Acceleration means speed is increasing with equal intervals of time. So its not possible according to my logic.
What is the similarity between constant speed and acceleration?
If the speed is constant then equal distances are covered in equal intervals of time If acceleration is constant then equal change in velocity occurs in equal intervals of time.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
If an object falls with constant acceleration the velocity of the object must?
Changing at a constant rate equal to acceleration.
What is contant acceleration?
motion of a body with constant acceleration, that means it has equal velocity in equal intervals if time.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.

What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
Which describes an object's velocity that changes by the same amount each second?
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
What is contants?
motion of a body with constant acceleration, that means it has equal velocity in equal intervals if time.
When can you have no acceleration?
To make acceleration equal zero. The velocity must be constant. For example, if velocity is constant at 10 m/s^2 its acceleration is zero. The same is true if velocity is 0 m/s^2.
Why is the slope of the force versus acceleration plot equal to the object's mass?
force directly proportional to acceleration. so F/a is remains constant. which is equal to mass of an object
