Unformatted text preview: . Now that we know this we can say that the ratio of the final momentum to the initial momentum is 1 (28) Likewise, we can say that the impulse of the system is 0 (29) 4.2 Inelastic Collisions In the next part of the experiment, you will perform a perfectly inelastic collision. You will do this by making one cart stick to the other cart. Because this collision is inelastic, kinetic energy is NOT conserved and the internal energy is NOT zero. Therefore we must first write the conservation of momentum which is written as (30) Sometimes you will see m1+m2 as M where M stands for the total mass of the system. Also we can define the momentum as (31) (32) Thus the ratio of the final momentum to the initial momentum is 1 (33) Also the impulse of the system is 0 (34) The change in internal energy is not equal to zero. Therefore once you find the change in internal energy using equation (19) we still use ∆ 1 7 (35) However this time (36) Therefore ∆ 0 8 (37)...
