a 10cm long spring is attached to the ceiling. when a 2.6kg mass is hung from it, the spring stretched to a length of 15cm.
what is the spring constant k
how long is the spring when a 4.0 kg mass is suspended from it

k= 2.6*9.8/.15 N/m
how long? x= F/k=4*9.8/above meters

k=2.6*9.8/.05 N/m Make sure you take the difference of the stretched string versus the one without any weight.
How long should be x = 4*9.8/k
