Continuing another problem from previous weeks, let's return to the train car 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) Separately calculate the change in momentum of each car. How do these values compare? (b) Approximating the duration of the collision as lasting 0.85 s, what is the force of inter- action between the two cars? In what direction does the force act on each car?

Transcribed Image Text:4.3. Continuing another problem from previous weeks, let's return to the train car 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 120000 kg, and the second car
initially has a velocity of 1.5 m/s.
(a) Separately calculate the change in momentum of each car. How do these values compare?
(b) Approximating the duration of the collision as lasting 0.85 s, what is the force of inter-
action between the two cars? In what direction does the force act on each car?
