When can a car have no acceleration but still be moving
a. when can a car have no acceleration but still be moving
b. when the car is still moving but coming to a stop
c. when the car starts at 0m/ and speeds up to 15m/s

When the velocity of the car is constant.

Explanation:

A car moving with no acceleration possesses a uniform velocity i.e the car velocity is not changing. This means that the car is covering a distance at a particular time interval "on a straight line". The velocity of the car is constant at that point that it has no acceleration because for a body to accelerates, the velocity of the body must be changing i.e the final velocity and the initial velocity must be different.

If the initial and final velocity of a body is the same, this means that the body is moving with a constant velocity and as such not accelerating.

the answer is to check all of them! they all apply well at least i think so!
