F=kx . F=ma . you have mass given and extension is known too. Oh, k is also given . So using F=kx and f=ma you can easily get the answer.

you subtracted the f spring - weight to get f net and then used a = f / m ???
yep i think...dont remember though
dude are you sure we had to minus the weight of the mass :(
I think I forgot to do so :(
would I get 2/3 ?

i dunno...but the weight would still act downwards opp to the direction of acc. so i think we have to subtract the weight. hope ya do.

i dont think u needed to subtract. cos in f=kx the f represents the net force already.. hmm i dno

what were the forces acting on the spring while it was just released? weight and upwards tension ?
