# A block of mass M is connected to another block of mass M2 by a massless spring of force constant K the blocks are resting on a smooth horizontal plane the blocks are initially at rest and the spring and stretch then a constant force f is applied on block m to pull it find the force on the block M2

When 2 Blocks are in Contact -

$F-f=m_{1}a$

$f=m_{2}a$

- wherein

$a=\frac{F}{m_{1}+m_{2}}$

$f=\frac{m_{2}F}{m_{1}+m_{2}}$

Hope it helps
