Problem 2, Toy Train: A small toy train consists of one locomotive and three cars. The car
behind the locomotive and the lst car have a mamiddle is larger and has a mass of 250 grams. When yss of 100 gou unpack the train the information sheet rams each, while tghe car in the
says that the locomotive will pull with a constant force. To impress your little sister (who is still
in high school) with your new knowledge of physics, you claim to be able to calculate the
tension in each of the three cables connecting the four parts of the train by making the following
mesister starts the trainb, yasurements: The locomotiveou concentrate just on the last car is 10 cm long while the other cars are all 8 cm longand you measure that it moves 1.5. As your
meters during the first 4 seconds. All the this motion is along a straight stretch at the beginning
of the track. [Kinematics equations are then given as useful information.]
Probleof the problem-solvingm 3, Equilibrium: strateg Here is most of a problem concepy, the focus step was referred totion [ as the Problem Conception.]i.e., focus; in an earlier version.
Please do a physics description and execute it. Mass of block A = 10 kg, coefficient of static
friction between table and block, 0.30. Question: What is the maximum weight, W, for which
the system will just remain in equilibrium? [An outline of the problem-solving strategy is then
given.]
