In an elastic collision
I. Energy is conserved
II. Energy is decreased
III. Energy is increased
IV. Linear momentum conserved
I only
I and IV only
II only
III only
Correct answer is B
In an inelastic collision, linear momentum is conserved and energy is decreased
Momentum and kinetic energy are conserved in elastic collision
