5) Suppose $X_1$ and $X_2$ are independent standard normal random variables. Therefore, $X_1$ and $X_2$ have density functions $f_{X_1}(x_1) = \frac{1}{\sqrt{2\pi}}e^{-\frac{1}{2}x_1^2}$ and $f_{X_2}(x_2) = \frac{1}{\sqrt{2\pi}}e^{-\frac{1}{2}x_2^2}$. By using the transformation technique, compute the joint probability density function of $Y_1$ and $Y_2$ if $Y_1 = X_1$ and $Y_2 = X_1 + X_2$.

1 Central-force motion Consider a particle of mass $m$ moving with a potential energy $U(r)$ that depends only on the distance $r$ between $m$ and the origin. If $L$ is its angular momentum about the origin, and $v$ its velocity, define a new vector by $A \equiv v \times L + U(r)r$ (a) (7 points) Calculate the time derivative of $A$ and show (using the chain rule) that it can be written as $\frac{dA}{dt} = \left(\frac{dU}{dr}r + U(r)\right)v.$ Hint: You'll need to use Newton's Second Law and Fitz (2.49). (b) (3 points) Using the properties of general orbits in a central potential, show that $L \cdot A = 0.$

Project A's costs is estimated to be RM800,000, with additional working capital of RM80,000. Part of the project cost is RM150,000 in equipment cost. The project is expected to generate RM250,000 in year one and RM450,000 in year two, RM500,000 in year 3 and final disbursement in year 4 is $ 30 \% $ of the project cost without the equipment cost. In the terminal year, the working capital will be recovered, as well as $ 20 \% $ of the equipment value. Assume the cost of the project of $ 5.18 \% $.
