In Example 7.5, we considered an elastic collision in one dimension in which one of the objects is initially at rest. Notice that mass 2 is the one that is initially at rest. Use the results for to answer the following problems. (a) Assume so that the incoming object is much more massive than the one at rest. Find Explain why the final velocity of the smaller object is much larger (in magnitude) than the final velocity of the bigger object. (b) Assume Explain why the final velocity of the smaller object is opposite its initial direction.
