Question

Give all five aspects of every problem: visual representation, principles/laws/assumptions of physics, symbolic representation - equations with variables, numerical solution, and check - refer to the principles you invoked and comment on the nature of the numerical solution.

On a low-friction track, two carts coupled together are initially moving to the right at 3.0 m/s. The rear cart has an inertia of 2.5 kg and he lead cart’s inertia is 4.0 kg. An explosive charge attached to the coupling is ignited remotely, releasing 30 J of energy. One-third of that energy is dissipated to incoherent forms. Determine the velocities of the carts just after the explosive separation.
