1. The problem statement, all variables and given/known data To stretch a spring a distance 2.96 cm from its unstretched length, an amount of work of 11.3 J must be done. How much work must be done to compress this spring a distance 4.01 cm from its unstretched length? I did this but am not sure if it is correct. Us = 1/2K[tex]\Delta[/tex]X2 2.96cm = .0296m 4.01cm = .0401m [tex]\Delta[/tex]X = .0105m What do I do from here? Would Us = 11.3J?
