Graph of the force magnitude \(F\) exerted on Cart 1 as a function of time \(t\).
Graph of the force magnitude \(F\) exerted on Cart 1 as a function of time \(t\).
Two carts, Cart 1 of mass \(m\) and Cart 2 of mass \(2m\), are held at rest on a horizontal, frictionless track with a compressed spring between them. At time \(t = 0\), the spring is released, pushing the carts in opposite directions until the spring completely detaches at time \(t_f\). A force sensor records the magnitude of the horizontal force \(F(t)\) exerted by the spring on Cart 1, producing the graph shown with shaded area \(A_0\). Which of the following statements correctly relates the features of the graph to the momentum and kinetic energy of the carts after they separate?
