Kinetic Energy and Inelastic Collisions

The six situations below show mass (m) and velocity (v) information for two carts prior to a collision.  Assume all collisions are Inelastic and any motion to the right is considered positive.

Rank from the greatest to the least on the basis of change in total kinetic energy of each collision.


Greatest   1____  2_____  3_____  4_____  5_____ 6______ 7_____ 8_____Least

Or, the change in kinetic energies of are the same for each situation.    ________  

Please carefully explain your reasoning.
