2.3. A train car is sitting on a level track when a second car moves in. The second car hits the first, their hitches engage, and they move together. Both cars have equal masses of about 120 000 kg, and the second car initially has a velocity of 1.5 m/s. (a) Draw a diagram that illustrates the situation and include an arrow representing the velocity vector of the second car and a separate arrow representing î, the unit vector for the coordinate system along the tracks. (b) Write vector expressions for both the velocity and momentum of the second car using at least two forms of vector notation that have been covered in class. (c) Just before the collision, what is the velocity of the center of mass of the system that includes both cars? Again, express this as a vector. (d) Just before the collision, what is the total kinetic energy of the system that includes both cars?

Two figure skaters are coasting in the same direction, with the leading skater moving at 5.5 m/s and the trailing skating moving at 6.2 m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50 heavier than the 50-kg leading skater, what is their speed after he picks her up?

Two train cars on a frictionless track have a completely inelastic collision in which they "couple" together. The car on the left has mass 16.1 tons and velocity 16.1 m/s to the right; the other train has mass 10.8 tons and velocity 13.1 m/s to the left. After the collision, what is the velocity of the pair fo cars? Your answer should be in tons times m/s, but you don't need to write the units, just the number. "To the right" is taken as positive, so make sure you have the sign right. (If your answer is positive, you don't need to write a "+" sign.)
