Homework Statement


If a object 1 & 2 collide as a perfectly inelastic collision, would they will both stop. Also If this same situation happened elastic? please explain if this is true or false and draw a free body diagram if possible.

Homework Equations


F=ma
newton second Law
KE=1/2ma

The Attempt at a Solution


true for inelastic, false for elastic because the momentum energy will transfer.

We have to realize that momentum is conserved for all collisions hence even in any inelastic collision kinetic energy cannot be completely lost unless the total initial momentum is zero. Think it over.
