Inelastic and elastic collision (please explain)

  1. Apr 18, 2016 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations
    F=ma
    newton second Law
    KE=1/2ma
    3. 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.
