Train cars are coupled together by being bumped into one another. suppose two loaded cars are moving toward one another, the first having a mass of 1.50×10 5 kg and a velocity of (0.30m/s)i, and the second having a mass of 2×10 5 kg and a velocity of (−0.12kg) i ^ . what is the energy lost in this inelastic collision?

7560 Joules

Explanation:

= Mass of first car =

= Mass of second car =

= Initial Velocity of first car = 0.3 m/s

= Initial Velocity of second car = -0.12 m/s

v = Velocity of combined mass

As linear momentum of the system is conserved

Energy lost is

The Energy lost in the collision is 7560 Joules

prolly a beacuse the momentuem the car has increases while going down hill
