An experiment is dоne in clаss with twо cаrs оn а track. Car 2 is at rest. Car 1 is pushed towards Car 2, and they stick together when they collide (magnet). Below are two trials: Trial Mass of Car 1 (kg) Mass of Car 2 (kg) Pre-collision velocity of Car 1 (m/s) Post-collision velocity of Car 1 (m/s) 1 0.20 0.20 0.80 0.40 2 2.1 4.2 0.60 0.30 Please answer the following questions: a) Does the experiment demonstrate an elastic or inelastic collision? How do you know? b) What is the post-collision velocity of Car 2 in Trial 1?
