a) All of the 9-ball’s energy and momentum are transferred to the 13-ball.
b) All of the 9-ball’s energy and some of its momentum are transferred to the 13-ball.
c) Some of the 9-ball’s energy and all of its momentum are transferred to the 13-ball.
d) In this collision, momentum is not conserved.
e) In this collision energy, is not conserved.
