Why is covering the brake with your foot important when you're backing out of any parking space?

Variable speed limit control for freeways. Refer to the Canadian Journal of Civil Engineering (January 2013) study of variable speed limits, Exercise $4.23$ (p. 201). Recall that a portion of an urban freeway was divided into three sections of equal length, and variable speed limits were posted (independently) in each section. The probability distribution of the optimal speed limit for each section follows (probabilities in parentheses). Section 1: $30 \mathrm{mph}(.05)$, $40 \mathrm{mph}(.25), 50 \mathrm{mph}(.25), 60 \mathrm{mph}(.45) ;$ Section $2: 30 \mathrm{mph}$ $(.10), 40 \mathrm{mph}(.25), 50 \mathrm{mph}(.35), 60 \mathrm{mph}(.30)$; Section 3: $30 \mathrm{mph}(.15), 40 \mathrm{mph}(.20), 50 \mathrm{mph}(.30), 60 \mathrm{mph}(.35) . \mathrm{A}$ vehicle adhering to the speed limit will travel through the three sections of the freeway at a steady (fixed) speed. Let $x$ represent this speed. List the possible values of $x$.

Write the word or phrase from the list that completes the sentence correctly. When you rest your foot on the brake pedal, you _____. 3 -second following distance, blind intersection, cover the brake, overtake, ride the brake, tailgate, traffic density.

A $30-\mathrm{lb}$ force $\mathbf{P}$ is applied to the brake pedal of an automobile as shown in given figure. Find the force $\mathbf{Q}$ applied to the brake cylinder and the reaction at support $A$.

On an automobile trip, the speed limit on one stretch of the road was 55 mph. A driver was driving at the speed limit and then drove 10 mph over the limit, then decelerated 7 mph, and finally, decelerated 13 mph. Interpret the speed using integers and determine his speed when last reported.

Why is it important to keep your right foot on the brake pedal while starting the engine?

Explain why you are able to see more in a convex mirror than in a flat mirror.

A truck is traveling at 30 m/s on a slippery road. The driver slams on the brakes and the truck starts to skid. If the coefficient of kinetic friction between the tires and the road is 0.20, how far will the truck skid before stopping? A. 230 m B. 300 m C. 450 m D. 680 m
