Dear student

Let a_cm be the acceleration of the centre of mass of the two particles. Then,

$a_{cm}=\frac{m_{1}a_{1}+m_{2}a_{2}}{m_{1}+m_{2}}$

Here since the particles are identical i.e, m₁=m₂=m(say)

$a_{cm}=\frac{m(a_{1}+a_{2})}{2m}=\frac{a_{1}+a_{2}}{2}$ (1)

Taking a₁=0(particle at rest) and a₂= f, we get

a_cm=f/2
