Two carts are involved in an inelastic collision. The dynamics cart A with mass 0.88 kg hits the collision cart B with mass 0.550 kg (initially at rest). The two carts collide and continue along together. The dynamics cart had an initial velocity of 0.24 m/s.
What is the initial kinetic energy of the two carts?
