Answer:
A. A car can still be moving without acceleration when it has some velocity.
B. A car can come to a stop when moving itself when it has some de acceleration.
C.A ca can start at 0 m/s and speed up to 15 m/s when it has some acceleration.
Explanation:
A. since the car has no acceleration the velocity of the car would help it moving.
B. when the car is moving with some velocity but coming to a stop this is possible of and only if it has some de acceleration
C. since the speed of the car increases from 0 to 15 m/s acceleration is involved. If the speed was constant there would be no acceleration involved.
Answer:
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.
