Solution

The correct option is A Has no acceleration

The center of mass velocity is the sum of each mass's momentum divided by the total mass of the system. The acceleration of the center of mass is the sum of all of the products of each mass and its acceleration divided by the total mass: Since Σ F = ma, ,It has no acceleration
