Physics System of Particles Rotational Motion Centre of Mass MCQ (Single Correct)

Two particles A and B, of mass m each, are joined by a rigid massless rod of length l . A particle P of mass m, moving with a speed w normal to AB, strikes A and sticks to it. The centre of mass of 'A + B + P' system is C.

A
The velocity of C before impact is u/3.
B
The velocity of C after impact is u/3.
C
The velocity of 'A + P' immediately after impact is u/2.
D
The velocity of B immediately after impact is zero.

The correct answer is:
CHECK THE SOLUTION.

(a, b, c, d)

As all three particles are part of the system, and impact between them produces no change in the velocity of their centre of mass. Also, ‘A + B’ can exert a force on B only along the rod, i.e., normal to u.
