29. Before Collision \"9 After Collision A block of mass '1 kg slides on a ictionless: horizontal surface with a velocity of3. In;If s to the right as shown above= and collides T.vith 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 T.vhether the collision is elastic or inelastic and provides a valid justication? (A) Elastic= because the total momentum before the collision equals the total momentum aer. Elastic: because some of the initial kinetic energy is converted to other forms of energy but the total energv is (B) conserved. (C) Inelastic= because the total momentum before the collision does not equal the total momentum aer. (D) Inelastic= because some of the initial kinetic energy is converted into nonmechanical energt
