Two pucks of equal mass collide. One puck (puck A) is stationary before the collision. After the collision the puck that was initially stationary moves along in the same direction in which the puck that hit it (puck B) was initially moving. Which of the following statements is correct if the total energy of the system is conserved during the collision (elastic collision)?
A. The puck B rebounds.
B. There isn’t enough information to answer the question.
C. Both pucks slide past the point of collision.
D. The puck B remains at the point of collision.
Homework Answers
D. The puck B remains at the point of collision
Because after the elastic collision punk A start moving with same speed as punk B moving previously and punk B remains at point of collision.
