|
|
it has a positive acceleration
|
|
|
it has zero acceleration
|
|
|
it has negative acceleration
|
|
|
it has a changing direction
|
Detailed explanation-1: -It has a zero acceleration. If something has a constant velocity, there is no acceleration!! Acceleration causes a change in a velocity and/or direction.
Detailed explanation-2: -Assertion :If the net force on a rigid body is zero, it is either at rest or moving with a constant linear velocity. Nothing else can happen. Reason: Constant velocity means linear acceleration is zero.
Detailed explanation-3: -Answer and Explanation: The answer to this question is a) the car travels the same distance in each second. We know that at constant velocity, the acceleration of an object is equal to zero. This means that the velocity of the object does not increase nor decrease.
Detailed explanation-4: -If an objects acceleration is zero, then its speed must remain constant.
Detailed explanation-5: -Therefore, In question there has been no mention of initial velocity or state of rest. So when the car moves in a constant velocity, the acceleration of the given body will also be constant, which is equal to zero.
