Chapter 11, Problem 17EAP
Three identical train cars, coupled together, are rolling east at speed v0. A fourth car traveling east at 2v0catches up with the three and couples to make a four-car train. A moment later, the train cars hit a fifth car that was at rest on the tracks, and it couples to make a five-car train. What is the speed of the five-car train?

You just turned 16 and thanks to some long hours at your job and some amazing parents you were able to purchase a
tesla. This 3000 kg car can go from 0 to 27m/s (about 60 miles per hour) in 2.5 seconds. You peel away from a stoplight
and do just that.
a. How far from the light are you when you hit 27 m/s? m
Since you live in the great city of Chicago and it is December and you encounter an icy patch. Your car experiences NO
friction on the ice patch but you also cannot apply any force. Another small (m-2300 kg) van coming towards you at 25m/s
in the other direction loses control and comes straight for you. They hit you and the two vehicles get tangled together and
continue to slide across the ice.
b. How fast are the cars going after the collision?
m/s
C. After you slide off the ice you hit the shoulder of the road with a coefficient of friction of 0.4 compared to the road. What
is your acceleration as they start to slide to a stop?
m/s/s
d. How much momentum do you have after you have…
