A rubber ball bounces off of a wall with an initial speed v and reverses its direction so its speed is v right after the bounce.
 
  As a result of this bounce, which of the following quantities of the ball are conserved? (There could be more than one correct choice.) A) the kinetic energy of the ball
  B) the momentum of the ball
  C) both the momentum and the kinetic energy of the ball
  D) None of the above quantities are conserved.

Question 2

  A) 0.734c
  B) 0.712c
  C) 0.981c
