39) You place two toy cars on a horizontal table and connect them with a light compressedspring as shown below. The spring tries to push the cars apart, but they are tied togetherby a thread. When the thread is burned, the spring pushes the cars apart. You decide toinvestigate how the final speed of car 2 depends on the mass of car 1. You run severalexperiments, changing m1 and measuring v2 while keeping the compression of the springand the mass of car 2 constant.MWWW.Which of the following v2-versus-m, graphs do you expect to obtain? Evaluate thegraphs by analyzing limiting cases. (Chapter 7, Question 13)a.b.c.V2V2V2

This problem can be approached by applying both momentum conservation and energy conservation. A…

It does not matter whether the orbit is circular or elliptical, no work is done. b.) The work the Sun does on Earth causes the tides. c.) Whether the orbit is circular or elliptical, work must be done to propel Earth around the Sun. d.) If the orbit is elliptical, work is done to speed up or to slow down Earth, depending on its location in orbit. e.) The work the Sun does on Earth accounts for Earth's changes of season.
