Question

Prove conservation of momentum of two objects moving on straight line and collide each other at time t

Answer 1

Answer:

Conservation 0f Momentum➫ A system in which the momentum of a system is constant if there are no external forces acting on the system.

Prove: Conservation 0f Momentum:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵

➧Let the Body A = m1 & B = m2

➧Let their velocity be u1 & u2

(u1 > u2)

➧Momentum of Body

A = m1u1 & B = m2u2

❱ Initial & Final momentum of System

➾ m1u1 + m2u2

◉ Body A exert force of Action

➾ Fᴀʙ on Body B.

◉ Body B exert force of Reaction

➾ Fʙᴀ on Body A.

▸ Fᴀʙ = Body A

➾ m1 (v1 - u1) / t

Answer 2

Explanation:

if collision does not takes place thir velocities remains constant forever and conservation of momentum of two objects cannot be applied
