(3) Given that the collision is completely inelastic and Glider 2 is initially at rest (V2,; = 0), please show that the energy loss rate always satisfies KfatKf2-Kil-Kizl = m2 |Ki,1+Ki,2] (hint: find m1+m2 the kinetic energies in terms of v1 ; and use them to compute the loss rate). Explain how this relation tells that the energy is not conserved upon a completely inelastic collision
