In a corner on a smooth horizontal surfaces we kept two masses
[IMAGE] and [IMAGE] attached to a spring
in natural length as shown. The spring has a spring constant 150 N/m.
Now [IMAGE] is suddenly given a velocity towards the
left at t = 0. After this spring attains natural length first at time
[IMAGE] sec and then next at time
[IMAGE]. If mass of [IMAGE] (in kg) is K
then K is

Show answer and solution
