In what case would momentum be constant

Web30 jun. 2024 · The law of conservation of momentum states that, when no external forces are acting on a system, then the momentum is conserved. Specifically, the total momentum of the system before and after any event remains the same. Consider a system of two point masses m 1 and m 2. Initially, these bodies were moving with the velocity v … WebQ. If two object collide and one is initially at rest (a) Is it possible for both to be at rest after collision. (b) Is it possible for any one to be at rest after collision. Ans. (a) No, because momentum will not be conserved in that case. (b) Yes, when masses of two object are equal and collision is perfectly elastic.
