A man starts pulling the block with constant force F = 3 N, when the massless spring
(of force constant 4.5 N/m) shown in figure is unstretched. At the instant spring is maximum
elongated, man leaves the block. The kinetic energy (in J) of the block, when it passes from
the equilibrium position after the release is -----.

I've seen that but had some doubts in that
Thats y i posted here for solution
1damn damn damn I always make the same mistake.....
[46][46][46]
use energy conservation
to get max elongation =4/3
apply energy conseravation again
ull get 4
