Answer:
smaller one
Explanation:
even though he is moving quicker doesn't mean he will be packing more force in the collision
A particle smaller than an atom or a <span>cluster of such particles </span>
For an inelastic collision where coefficient of restitution,e, is equal to 0, the momentum is conserved but not the kinetic energy. So, there is addition or elimination of kinetic energy.
On the otherhand, when e = 1, like for an elastic collision, kinetic energy and momentum is conserved. Thus, the system's kinetic energy is unchanged.
