Consider the homogeneous 2nd-order Linear Differential Equation: $x'' + 5x' + 6x = 0$ $x'' + 5x' + 6x = 0$; $x(0) = 2$, $x'(0) = -1$. a. Solve this equation using the techniques from this section. b. Here are five matrices, each with the same eigenvalues (-2, -3) as the equation above. Which one represents $x'' + 5x' + 6x = 0$ written as a system of two 1st-order differential equations? i. $\begin{pmatrix} -5 & 3 \\ -2 & 0 \end{pmatrix}$ ii. $\begin{pmatrix} 0 & -2 \\ 3 & -5 \end{pmatrix}$ iii. $\begin{pmatrix} -4 & -2 \\ 1 & -1 \end{pmatrix}$ iv. Correction: signs are opposite giving eigenvalues as {2,3} instead of {-2,-3). Please use opposite signs for matrix A: {{0,1},{-6,-5}} v. $\begin{pmatrix} 0 & -1 \\ 6 & 5 \end{pmatrix}$ $\begin{pmatrix} -2 & 3 \\ 0 & -3 \end{pmatrix}$ c. Graph all five matrices with the initial condition $x = 2$, $y = -1$ (using a Phase Plane plotter (you can use this one or Sage tools for Section 2.2.41 of our book, or one of your choosing). What is different about the four solution curves? What is the same? The idea here is to delineate what the eigenvalues tell us about the solution curves compared to what the eigenvectors tell us.

A proton moves in a particle accelerator of diameter 40 cm perpendicular to a Magnetic Field equal to 0.150 T. Find (i) the speed of the proton and (ii) the period of the motion, (iii) the work done on the proton by $\vec{F}_B$, (iv) the kinetic energy of the proton when it emerges out of the cyclotron accelerated?\nNote: Do not write down the formula directly. Explain circular motion in terms of $\vec{B}$, $\vec{F}_B$, and $\vec{v}$. [Hint: Rotational Kinetic Energy $K = \frac{1}{2}Mr^2\omega^2$]

Family Need Method Johana and her spouse are in good health and have reasonably secure careers. She makes about $65,000 annually and has opted for life insurance coverage of three times her salary through her employer. One of her most important financial goals involves building an education fund of $80,000 to cover the cost of a four-year university program for her two children ages 2 and 4. To date, she has accumulated $15,000 toward this goal in an RESP. Johana owns a home with a $280,000 remaining mortgage balance. Other debts include a $10,000 car loan, $5,000 student loan, and $3,000 charged to credit cards. In the event of her death, Johana wishes to leave her
