In Example 8.7 (Section 8.3), where the two gliders in Fig. 8.15 stick together after the collision, the collision is inelastic because K2 < K1. In Example 8.5 (Section 8.2), is the collision inelastic? Explain.

Solution to 8DQ Step 1 The values here are taken from Example 8.5 section 2. Mass of glider A, m =0.5kg a Mass of glider B, m =0.3kg b Initial velocity of Glider A, v =2m/s a Initial velocity fo glider B, v =-2m/s b Final velocity of glider B, v’ =2m/s b Final velocity of glider A, v’ =-0.4m/sa……………………(As computed in the example)
