Two cars collide,lock bumpers,and eventually slide to a stop due to friction with the roadway.During this entire process,mechanical energy and momentum are both conserved.

Question

Quizplus · Accepted Answer

Mechanical energy is not conserved in this situation, as some of it is converted into kinetic energy, sound energy, heat energy, and deformation energy. However, momentum is conserved since the total momentum before and after the collision is the same.
