Can a body have acceleration without having velocity?

Can a body have momentum without energy?

Assertion : A body cannot have energy without possessing momentum but it can have momentum without having energy. Reason : Momentum and energy have same dimensions.

Statement-1 : A body with negative energy cannot have momentum. Statement-2 : This is because momentum can be positive only.
