b. What is the momentum of B before the collision?
c. What is the velocity of ball A after the collision?
d. What is the velocity of ball B after the collision?
e. What is the momentum of A after the collision?
f. What is the momentum of B after the collision?
g. What is the impulse of ball A ?
h. What is the impulse of ball B ?
