10.74. Model: Mechanical energy and momentum are conserved during the expansion of the spring. Visualize: Please refer to Figure CP10.74. Solve: Example 10.8 is a very similar problem, except that the objects are initially at rest. We can use the solution from Example 10.8 for this problem in a reference frame S in which the two carts are initially at rest, then transform the answer to the frame S in which the carts are initially moving. Thus in the S frame, () 2 i f 2 2 2 1 1 x kx v m m m Δ = + 2 ff 12 1 xx m vv m =− Let the 100 g cart be Cart 1 and the 300 g cart be Cart 2. With
