... what is the question?

anonymous · Answer

are you asking for the spring constant k?

anonymous · Answer

knowing that the force that compresses the spring is the over-all wight W = mg of the safe...
W = mg = 900kg(9.8m sec^-2) = 8820N = F = kx
where x is the distance of compression = 60cm =0.6m
then...
k = F/x = 8820N/0.6m = 14700 N/m
