One common form of aggressive driving is for a trailing driver to repeat a pattern of accelerating suddenly to come close to the car in front and then braking suddenly to avoid a collision. One way to monitor such behavior, either remotely or with an onboard computer system, is to measure vehicle jerk, where jerk is the physics term for the time rate of change of an object's acceleration along a straight path. Figure $2.38$ is a graph of acceleration $a$ versus time $t$ in a typical situation for a car. Determine the jerk for each of the time periods: (a) gas pedal pushed down rapidly, $2.0 \mathrm{~s}$ interval, (b) gas pedal released, $1.5 \mathrm{~s}$ interval, (c) brake pedal pushed down rapidly, $1.5 \mathrm{~s}$ interval, (d) brake pedal released, $2.5 \mathrm{~s}$ interval.

Of employed U.S. adults age 25 or older, $90.4 \%$ have completed high school, while $34.0 \%$ have completed college. For $H=$ completed high school, $C=$ completed college, and assuming that one must complete high school before completing college, construct a tree diagram to assist your calculation of the following probabilities for an employed U.S. adult:

b. $P(C \mid H)$

During a solid-state physics lab, you are handed a cylindrically shaped sample of unknown magnetic material. You and your lab partners place the sample in a long solenoid that has $n$ turns per unit length and a current $I$. The values for magnetic field $B$ within the material versus $n I$ are given below. Use these values to draw $B$ versus $B_{\text {app }}$ and $K_{\mathrm{m}}$ versus $n I$, where $B_{\text {app }}$ is the field due to the current $I$ and $K_{\mathrm{m}}$ is the relative permeability of the sample.

$$\begin{array}{lllllllll}n I, \mathrm{~A} / \mathrm{m} & 0 & 50 & 100 & 150 & 200 & 500 & 1000 & 10000 \\ B, \mathrm{~T} & 0 & 0.04 & 0.67 & 1.00 & 1.2 & 1.4 & 1.6 & 1.7\end{array}$$

A physics teacher had a bowling ball suspended from a very long rope attached to the high ceiling of a large lecture hall. To illustrate his faith in conservation of energy, he would back up to one side of the stage, pull the ball far to one side until the taut rope brought it just to the end of his nose, and then release it. The massive ball would swing in a mighty arc across the stage and then return to stop momentarily just in front of the nose of the stationary, unflinching teacher. However, one day after the demonstration he looked up just in time to see a student at the other side of the stage push the ball away from his nose as he tried to duplicate the demonstration. Tell the rest of the story and explain the reason for the potentially tragic outcome.
