Which of the following is true :
(1) Momentum is conserved in all collisions but
\( \mathrm{P} \) kinetic energy is conserved only in inelastic

W collision
(2) Neither momentum nor kinetic energy is conserved in inelastic collisions.
(3) Momentum is conserved in all collisions but not kinetic energy
(4) Both momentum and kinetic energy are conserved in all collisions
