A particle of mass m moving with a velocity ((3 i +2 j ) m / s ) collides with stationary body of mass M and finally moves with velocity ((-2 i + j ) m / s ) then (A) Impulse received by (m=m(5 i -5 j ) ) (B) Impulse received by (m=m(-5 i - j ) ) (C) Impulse received by ( M = m (5 i + j ) ) (D) Impulse received by (M=m(5 i - j ) ) then correct statements are

Options

  1. AB, C
  2. BA, C
  3. CB, D
  4. DA, D

Correct answer

A. B, C

Step-by-step solution

( aligned & I=m v & =m[(-2 i + j )-(3 i +2 j )] & =m[-5 i - j ] Impulse on m & Impulse on M=-( Impulse on m) & =m(5 i + j ) aligned )
