Question

3)(1-3)
Three identical masses are kept at the corners
of an equilateral triangle ABC. A moves
towards B with a velocity V. B moves towands
C with velocity V, and C moves towards A
with same velocity V. Then the velocity of
centre of mass of the system of particles is
1 V
2) zero 3) 3V
4 -​

Answer 1

the velocity of centet

of mass is 3V m s

Answer 2

Answer:

ZERO

Explanation:

Using Vcm =iˆVx+jˆVy

where Vx=mV(x)1+mV(x)2+mV(x)2 / 3m=0

Vy=mVy1+mVy2=mVx / 33m=0
