The two meet in a head-on collision and come to a complete stop. The young bull has a mass of 503 kg and was running at a speed of 5.6 m/s. The older bull has a mass of 721 kg. The collision takes place on an icy patch, so you can ignore friction. (a) What was the speed of the older bull? (b) How many joules of energy were "lost" in this collision?
