An air-track glider undergoes a perfectly inelastic collision with an identical glider that is initially at rest. What fraction of the first glider’s initial kinetic energy is transformed into thermal energy in this collision?
A 4.0 kg box slides on a horizontal frictionless table and collides with a 1.6 kg box initially at rest on the edge of the table, at height h = 1.0 m. The speed of the 4.0 kg box is 3.6 m/s just before the collision. If the two boxes stick together because of packing tape on their sides, what is their kinetic energy just before they strike the floor? (Your result must be in Joules and include 1 digit after the decimal point. Maximum of 2% of error is accepted in your answer. Take g=9.8 m /s 2.)
Two carts of equal mass are on a horizontal, frictionless air track. Initially cart A is moving toward stationary cart B with a speed of vA. The carts undergo an inelastic collision, and after the collision the total kinetic energy of the two carts is one-half their initial total kinetic energy before the collision. What is the speed of each cart after the collision?

A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them (Fig. P8.7).
