Question

Two blocks of masses m and 2m are connected by a massless spring kept on the horizontal smooth floor. At some instant two forces 2F and F act on the blocks respectively such that the acceleration of mass m is a0 then find the magnitude of acceleration of mass 2m

Answer 1

As the acceleration of block of mass m is a_0 , the total force on it will be m(a_0) . Now calculate the net force on 2m block and equate it to 2m(a).
Solution is in the attachment.
