no
yes!A2. The real problem is deciding when a body is at rest - or is it just the rest of the universe that is moving?
No, a body cannot have acceleration while at rest. Acceleration is the rate of change of an object's velocity, meaning it requires the object to be in motion. When an object is at rest, its velocity is zero, so there is no change in velocity, hence no acceleration.
To come to rest, its velocity must change, therefore it will accelerate. Once it is at rest, if it remains at rest, it will no longer accelerate, i.e., its acceleration will be zero.
If a body starts from rest, it means its initial velocity is zero. In this case, if the body is in motion, it has undergone acceleration to reach that velocity. Therefore, the acceleration of the body must be non-zero, indicating a change in velocity over time.
Yes, it is possible for the speed to be 0 while the acceleration is non-zero. This occurs when the object is momentarily at rest (speed is zero) while still experiencing acceleration due to a change in its velocity.
No a boday while rest cannot be in acceleration because of the momentum of the body ...........................

Zero.
zero
For a body to be momentarily stopped, its velocity must be zero at that instant. This means that there is no net force acting on the body, causing it to remain at rest for that brief moment.

acceleration is a relative quantity . state of rest or motion is also relative . if two body is in rest or moving with same velocity and having same acceleration then one is in state of rest with respect to other . suppose a person sitting in a train then he is in rest with respect to train but he is moving with the acceleration of train with respect to the ground.
