(????) A large container made to hold water has the equation z = 5(x^2 + y^2)^{5/2}. (The $z$-axis points up.) (a) Find a formula for $V(z)$, the volume of water in the container when its depth is $z$. ANSWER: $V(z) = $ (b) Suppose that the container is filled to a depth $H > 0$. At a certain instant, a hole develops at the origin and water starts to drain out. This makes the water depth $z$ a decreasing function of time; the water depth has dropped to $H/2$ exactly 135 minutes after draining begins. Find the first time when all the water is gone; call this $T$. ANSWER: $T = $ Background: According to Bernoulli's Law, the instantaneous rate of volume loss from a container like ours is proportional to the square root of the water depth.

CH 05 HW Problem 5.64 Constants Researchers often use force plates to measure the forces that people exert against the floor during movement. A force plate works like a bathroom scale, but it keeps a record of how the reading changes with time. (Figure 1) shows the data from a force plate as a woman jumps straight up and then lands.

Question 3 (8 pts total) Match the type of interrupt with its description 3.1 Program interrupt ____ (2 pts) 3.2 Timer interrupt ____ (2 pts) 3.3 I/O interrupt ____ (2 pts) 3.4 Hardware interrupt ____ (2 pts) a. Generated by some condition that occurs as a result of an instruction execution, such as arithmetic overflow, division by zero, attempt to execute an illegal machine instruction, or reference outside a user's allowed memory space. b. Generated by an I/O controller, to signal normal completion of an operation, request service from the processor, or to signal a variety of error conditions. c. Failure Generated by a failure such as power failure or memory parity error. d. Generated by a timer within the processor. This allows the operating system to perform certain functions on a regular basis.

x1[n] and x2[n] are 10 point sequence. The relationship between them is \hat{x}_2[k] = X_1(z)|_{z=2e^{-j(\frac{\pi k}{5} + \frac{\pi}{10})}, where \hat{x}_2[k] is DFT of x2[n] and X_1(z) is the z-transform of x1[n]. Give an expression for x2[n] in terms of x1[n]. Hint: Type in the exponential function exp(x) as 'exp(m)', j as '%i', and \pi as '%pi' x2[n] = x1[n]
