Question

a system consists of two identical particles one particle is at rest and other particle has an accelration a. the centre of mass of the system has an acceleration of

Answer 1

please explain question clearly 

Answer 2

Answer:

Acceleration of centre of mass, Acm = a/2

Explanation:

Given;-

     Masses are= m ( for both the particles )

One particles is at rest while another has an acceleration of a.

For the given system, we know that the acceleration of centre of mass is given by the formula;-

         Acm = (m₁a₁ + m₂a₂) / (m₁ + m₂)

Putting the given values in the formula, we get;-

         Acm = (m(0) + ma) / ( m + m )

         Acm = ma / 2m

         Acm = a/2
