1. The problem statement, all variables and given/known data

Which of the following statements is true for collisions?
a) Momentum and Kinetic energy are always conserved in collisions.
b) Momentum can only conserved in elastic collisions.
c) Kinetic energy is conserved only in inelastic collisions.
d) Only kinetic energy can be conserved in elastic collisions.
e) None of these are true for collisions.


3. The attempt at a solution
i believe the answer is e. but thought it could be c but then momentum can also be conserved so i concluded e
