1 3 0 m s 1 kg Before Collision 2 kg After Collision 1 kg 2 kg A block of mass 1 kg slides on a frictionless horizontal surface with a velocity of 3 0 m s to the right as shown above and collides with a block of mass 2 kg that is at rest As a result of the collision the 1 kg block comes to rest Which of the following correctly states whether the collision is elastic or inelastic and provides a valid justification A Elastic because the total momentum before the collision equals the total momentum after B Elastic because some of the initial kinetic energy is converted to other forms of energy but the total energy i conserved C Inelastic because the total momentum before the collision does not equal the total momentum after
