## Homework Statement

Two blocks of mass m1 and m2 (m2 = 2 kg ; m1 = 3 kg)are connected with a spring moving on smooth plane. The acceleration of block of mass m2 is 2 ms

^{-2}, find acceleration of block with mass of 3kg.

**2. The attempt at a solution**

Let external force of F be applied on Block m2.

∴ By only considering m2, we get

F - T = 6

and for block m1

T = 2a

and by newton's law of system (Fnet = m

_{1}a

_{1}+m

_{2}a

_{2}+m

_{3}a

_{3}+........)

F = 6 + 2a

But by solving these three equations, i am not getting the answer.

Plz help...........

Thanks
