Question
A body cannot have zero velocity but non zero momentum together.
✓

Answer

True.
Explanation:
Momentum is the product of velocity and mass. Now, if a body possess zero acceleration this means that there is no change in velocity, that doesn't means that the velocity will have to be zero. thus, momentum is only zero when the velocity of the body is zero as because mass cannot be zero if the object exists.
