We will notify you when Our expert answers your question. (Reference M-J/2012/12),i am confused in choosing A and D Q. 2 balls of clay , the first of mass 0.5kg,the other of mass 0.75kg approach each other ,each travels with a velocity of 0.5m\s,after the collision they stick together,what is the total energy after co. What is the final velocity of ball 1 if the collision is perf. What is the speed of mass one after the collision if the collision is completely elastic, Ball 1, with a mass of 150 g and traveling at 12 m/s, collides head-on with ball 2, which has a mass of 320 g and is initially at rest.
