Want this question answered?
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.
As long as it has a non-zero velocity, it will have a non-zero momentum.
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
Yes, you can. Zero acceleration simply means there is no CHANGE in velocity. It doesn't mean there is no velocity.
no

When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.

it cannot be same as the acc. is not zero
Yes, just as the acceleration is reversing your direction of movement.
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
