(1) The momentum of a system of bodies is equal to the sum of the momentum of bodies of the system. This given statement is a completely true statement.
(2) The criterion for distinguishing the impacts in frontal, eccentric, and lateral is the position of the carriers of the velocities of the bodies before they collide. Hence, this given statement is a false statement
(3) The measure of momentum p and the kinetic energy K of a body of mass m are related by the relation k = (p^2)/m. Hence, this given statement is a false statement.
(4) The momentum and acceleration of a body are always beautiful vectors. Hence, the given statement is a completely true statement.
(5) If the momentum of a moving body system is zero then the kinetic energy of the system is also zero. Hence, the given statement is completely a true statement.
