Two pucks, \(A\) and \(B\), slide on a frictionless horizontal surface in the \(xy\)-plane.

Puck \(A\) has mass \(m_A = 2.0\text{ kg}\) and initial velocity \(\vec{v}_{Ai} = (4.0\hat{i})\text{ m/s}\), and puck \(B\) has mass \(m_B = 1.0\text{ kg}\) and initial velocity \(\vec{v}_{Bi} = (3.0\hat{j})\text{ m/s}\).

The pucks collide, and immediately after the collision puck \(B\) has velocity \(\vec{v}_{Bf} = (4.0\hat{i} - 1.0\hat{j})\text{ m/s}\).

Which row in the table correctly indicates how the kinetic energy of puck \(B\), the total kinetic energy of the two-puck system, and the speed of the center of mass of the system change as a result of the collision?

	Kinetic Energy of Puck \(B\)	Total Kinetic Energy of System	Speed of Center of Mass
(A)	Decreases	Decreases	Decreases
(B)	Decreases	Remains constant	Remains constant
(C)	Increases	Increases	Remains constant
(D)	Increases	Decreases	Remains constant
