If a 1305 kg train car on a one dimensional track, moving at 4 m/s north, hits and bounces off a second train car with a mass of 3172 kg , moving at 10 m/s south, find the magnitude of the final speed of the first car (the second car will have a different speed, most probably in the opposite direction).

If a 1305 kg train car on a one dimensional track, moving at 4 m/s north, hits and
bounces off a second train car with a mass of 3172 kg , moving at 10 m/s south, find
the magnitude of the final speed of the first car (the second car will have a different
speed, most probably in the opposite direction).
Hint: One dimensional problem, call north positive. Use the "hit and bounce" or
elastic formula that goes with car #1
2m,
– m2
2v, +
т + m,
т
-
v',
т + m,
2m,
m, – m,
-V2
-
+ m2
т + m,
Also, a positive answer would indicate motion to the north and a negative answer
would show southward motion - leave positive/negative in your answer.
