Cart 1 approaching Cart 2, which is attached to a wall via a spring.
Cart 1 of mass \(M\) is moving with speed \(v_0\) toward Cart 2 of mass \(2M\) on a horizontal frictionless track. Cart 2 is initially at rest and is attached to a rigid wall by a horizontal ideal spring of spring constant \(k\). The spring is initially at its equilibrium length. Cart 1 collides with and sticks to Cart 2. Which of the following is the best expression for the speed of the two-cart system immediately after the collision?
