You are standing 2.5 m directly in front of one of the two loudspeakers shown in the figure. They are 3.0 m apart and both are playing a 686 Hz tone in phase. (Figure 1) You may assume that the room is 20° C in this example such that the speed of sound is 343 m/s. What is the largest distance from the top speaker at which you would hear a minimum sound intensity? dmax = 17.9 m Correct Part B Previous Answers In the previous part, you figured out that the difference in path length between the two speakers must be a multiple of a half wavelength to get destructive interference. A path length difference of exactly half of a wavelength gave you the answer above. What distance will result if the path difference is 1.5 λ? d2 = Submit Request Answer Part C Complete previous part(s) Figure < 1 of 1 2.5 m 3.0 m Walk Provide Feedback ? m Next >

Question 4 15 pts For a mass-spring-damper system the governing equation is: $$m\ddot{x} + c\dot{x} + kx = 0$$ m=4 kg k=81 N/m The system is critically damped. If the initial position is 0.3 m and the initial velocity is 0.1 m/s, what is the position at t = 1.5 sec using x.xxx format? Question 5 15 pts For a mass-spring-damper system the governing equation is: $$m\ddot{x} + c\dot{x} + kx = 0$$ m=6 kg c=81 N*s/m k=36 N/m Determine the position, using x.xxx format, at t = 4 sec if the system starts from $$x(0) = x_0$$ =0.5 m with an initial velocity of 0.2 m/s Question 6 15 pts For a mass-spring-damper system the governing equation is: $$m\ddot{x} + c\dot{x} + kx = F(t)$$ m=8 kg c=4 N*s/m k=85 N/m F(t) = 0.7 N Determine the position, using x.xxx format, at t = 5 sec if the system starts from $$x(0) = x_0$$ =0.5 m with an initial velocity of 0 m/s ---

8. Combine Exercises 4 and 7 and the definition (4.3) to find $e^A$ where A = $\begin{bmatrix} 1 & 1 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{bmatrix}$ (a) $\begin{bmatrix} 2 & 1 & 0 \\ 0 & 2 & 0 \\ 0 & 0 & 3 \end{bmatrix}$ (b) $\begin{bmatrix} 1 & 1 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 2 \end{bmatrix}$ (c) 4. Show that if $A = \begin{bmatrix} \lambda_1 & 0 & 0 \\ 0 & \lambda_2 & 0 \\ 0 & 0 & \lambda_3 \end{bmatrix}$, $e^A = \begin{bmatrix} e^{\lambda_1} & 0 & 0 \\ 0 & e^{\lambda_2} & 0 \\ 0 & 0 & e^{\lambda_3} \end{bmatrix}$. 7. If A and B are n x n matrices such that AB = BA, show that $e^Ae^B = e^{A+B}$. The sum of this series is denoted $e^A$, that is, $e^A = \sum_{k=0}^\infty \frac{A^k}{k!}$. (4.3)
