The motor in rocket A is twice as powerful as the motor in rocket B.
Reason: For the same mass, force = ma, so A's thrust is twice B's. Power = force × velocity, so at the same speed the power scales with force; hence A's motor delivers twice the power. (Note: at v = 0 instantaneous mechanical power = 0, so the comparison assumes nonzero/like speeds.)
