In class we havnt really talked about high k constant and only worked with small k constants. So it seemed a little skeptical as I didnt think it should be that high. Appreciate the help.
Oh Sorry, was on my phone and rushing.
I expanded ET1=ET2 to get
(Total energy at top) 1/2mv^2+mgh = 1/2kx^2 (Total energy at bottom)
Rearanged i got
k = (mv^2+2mgh)/x^2
so [(73)(20)^2+2(73)(9.8)(52)]/0.465^2
=479137.945N/m
