**1. Homework Statement**

Two cars of 540 kg and 1400 kg collide head on while moving 80 km/h in opposite directions. After the collision, the automobiles remain locked together.

Find the velocity of the wreck, the kinetic energy of the two-automobile system before and after the collision, and find the acceleration of the passenger compartment of each vehicle given that the front end of each car crumpled by 0.6 m during the collision.

(I've already found the velocity and energies, I just need help with the acceleration.)
