Type: Match the Following-match the column-Easy-Class 11

Match Column-I with Column-II.

Column-IColumn-II
(a) Momentum conservation in elastic collision(i) m1v1i = m1v1f + m2v2f
(b) Kinetic energy conservation in elastic collision(ii) 1/2 m1v1i^2 + 1/2 m2v2i^2 = 1/2 m1v1f^2 + 1/2 m2v2f^2
(c) Work-energy principle for stopping force(iii) W = -2000 J
(d) Momentum conservation for inelastic collision(iv) m1v1i = (m1 + m2)vf
A

a-i, b-ii, c-iii, d-iv

B

a-i, b-iv, c-iii, d-ii

C

a-ii, b-i, c-iv, d-iii

D

a-iv, b-iii, c-ii, d-i

Correct Answer

Option A

Detailed Explanation

In the context of elastic collisions, momentum conservation is accurately represented by the equation m1v1i = m1v1f + m2v2f and kinetic energy conservation is represented correctly by 1/2 m1v1i^2 + 1/2 m2v2i^2 = 1/2 m1v1f^2 + 1/2 m2v2f^2. The work done by the stopping force is calculated as W = -2000 J, and inelastic collision momentum conservation is given by m1v1i = (m1 + m2)vf.
