Jane buys only two goods: good 1 and good 2. Her preferences are complete, reflexive, and transitive. Her preferences are also (strongly) monotonic. The price of good 1 is $3 per unit, the price of good 2 is $2 per unit, and her income is $120. (1) Graph the budget line and the budget set that she faces. (2 points) (The horizontal axis measures the quantity of good 1.) (2) Consider the following consumption bundles. Consumption Bundle Units of Good 1 Units of Good 2 A 20 30 B 10 55 C 40 20 D 30 45 E 20 20 F 10 45 An addtional information about Jane's preferences is that she is indifferent between consumption bundle A and consumption bundle B. Find Jane's best affordable consumption bundle (or her optimal consumption bundle) among the above consumption bundles. Explain your answer. (4 points)

3. (a) Determine the relative speed of an electron $\beta \equiv v/c$ that has a kinetic energy of 5 MeV. Give your answer with four significant figures precision. (10 points) (b) An important relativistic relationship for a particle of mass $m$ moving at speed $v$ is: $E^2 = p^2c^2 + E_0^2$, where $E = \gamma mc^2$ is the total energy of the particle, $E_0 = mc^2$ is its rest mass energy, $p = \gamma mv$ is its momentum, and $\gamma = 1/\sqrt{1 - (v/c)^2}$. Show that any massless particle ($m = 0$) always travels at the speed of light in vacuum $c$. (10 points) (c) Calculate the de Broglie wavelength $\lambda$ of an electron with kinetic energy of 10 MeV. (10 points)
