Guided Problem 7.4 An unequal match On a low-friction track, two carts coupled together are initially moving to the right at 2.0 m/s. The rear cart has an inertia of 2.0 kg, and the lead cart's inertia is one-third of that. An explosive charge attached to the coupling is ignited remotely, releasing 27 J of energy. One-third of that energy is dissipated to incoherent energy, such as noise, thermal energy, and damage to the carts. Use the Earth reference frame for the following tasks. (a) Deter mine the velocities of the carts just after the explosive separation. (b) Draw a bar diagram showing the energy distribution before and after the explosive separation.
