7. A slender rod CD, of length $L$ and mass $m$ is placed upright as shown on a frictionless horizontal surface. A second and identical rod AB is moving along the surface with a velocity $v_1$ when its end B strikes squarely end C of rod CD. Assuming that the impact is perfectly elastic, determine immediately after the impact, (a) the velocity of rod AB, (b) the angular velocity of rod CD, (c) the velocity of the mass center of rod CD.

QUESTION 6 Doug, the dog, catches a ball 45% of the time. Doug's owner tosses a ball to Doug 6 times and counts the number of times Doug catches the ball. Which of the following is a true statement? This a binomial situation because Doug makes a fixed number of attempts to catch the ball, the probability that he catches the ball is fixed, and we assume his attempts are independent. This is not binomial because we don't know how many times Doug will catch the ball. This is not binomial because it's possible that Doug catches the ball all 6 times. This is not binomial because Doug may not catch the ball at all in the 6 attempts.

QUESTION 13 Labeling Pre-Lab: Foot Muscles & Associated Structures Dorsum of Foot The muscles of the dorsum include the extensor hallucis brevis m. and the extensor digitorum brevis m. The extensor hallucis brevis m. (Label: ____) extends the joint between the first metatarsal and the phalanges of digit 1. The extensor digitorum brevis m. (Label: ____) extends the digits 2-4. The two brevis muscles are the shorter version of the longus muscles located in the anterior leg compartment. Notice how the tendons of these muscles do not attach to a distal phalanx like the tendons of the longus muscles of the anterior leg. It is also interesting that extensor digitorum brevis only attaches to digits 2-4, rather than 2-5

The initial heat distribution over a steel plate is given by the function. Create a MATLAB script to make a mesh plot and surface plot of the given function $f(x,y)$ for the interval $-2.1 \leq x \leq 2.1$ and $-6 \leq y \leq 6$ with a step size of 0.01. Using subplot, plot the absolute value of $f(x,y)$ versus $x$ and $y$ also. $u(x, y) = 80y^2e^{-x^2-0.3y^2}$. Use Magenta 2D dashed line and add title, labels, legend and grid on the plot.
