Question 8 (1 point)
In a partially elastic collision between two objects with unequal mass:
1) the velocity of one will increase by the amount that the velocity of the other
decreases.
2) the momentum of one will increase by the amount that the momentum of
the other decreases.
3) the energy of one increases by the amount that the energy of the other
decreases.
4) the total momentum of the system will decrease.
5) both choices A and B are valid.
