An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs to gain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals). One of the survey questions was, “During the average workday, how many hours do you spend attending meetings?” For the subsample of legal professionals (n = 250), the mean response was M = 2.0 hours, with a sample standard deviation of s = 4.2 hours. The estimated standard error is sMM = .

If the velocity of a particle is defined as $v(t) = (0.8t^2i + 12t^{1/2}j + 5k)$ m/s, determine the magnitude and coordinate direction angles $\alpha$, $\beta$, $\gamma$ of the particle's acceleration when $t = 2$ s.

2. Find the weak form for the following boundary value problem: $\begin{cases} u_{xx} + u = 0 \\ u(0) = 0 \\ u(1) = -1 \end{cases}$ 3. Using the trial function $u^h(x) = a \sin(\pi x)$ and weighting function $w^h(x) = b \sin(\pi x)$ find an approximate solution to the following boundary value problems by determining the value of coefficient $a$. For each one, also find the exact solution using Matlab and plot the exact and approximate solutions. (One point each for: (i) finding $a$, (ii) finding the exact solution, and (iii) plotting the solution) a. $\begin{cases} u_{xx} - 2 = 0 \\ u(0) = 0 \\ u(1) = 0 \end{cases}$ b. Modify the trial function and find an approximation for the following boundary value problem. (Hint: you will need to add an extra term to the function to make it satisfy the boundary conditions.) $\begin{cases} u_{xx} - 2 = 0 \\ u(0) = 1 \\ u(1) = 0 \end{cases}$
