Question

Consider the following two statements A) Linear momentum of the particles is zero
B) kinetic energy of a system of particals is zero​

Answer 1

Answer:I does not imply II but II implies I

Explanation:Let's say two bodies of equal masses are in motion with same velocity in opposite direction, then the linear momentum of the system is zero, but the kinetic energy is not zero.But when kinetic energy  of the system of particles is zero, kinetic energy of each has to be zero i.e speed of each particle is zero.. Hence, momentum of the system of particles is zero.
