Answer #1

Yes for a particle moving with uniform acceleration it is possible to reverse it's direction of motion. Take example of vertical motion, if a ball is thrown upwards it's velocity decreases but the acceleration is uniform. At the highest point velocity becomes zero and ball starts to fall back, the direction of motion changes but the acceleration remains constant.

Acceleration doesn't guide the motion or the direction of motion doesn't depend on acceleration.
