Question

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 ​

Answer 1

When the velocity of the car is constant.

Step-by-step 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.

Answer 2

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.

Step-by-step 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.
