i got part c by doing the following
let x = max compression
U1-fs=0.5kx[SIZE="1"]^[SIZE="1"]2
s= 4+x
k=120N/m
2*9.8*(4+x)sin53.1-2.35(4+x)=60x[SIZE="1"]^2
solving the quadratic gives you x=1.06m.
is this remotely correct?
Homework Statement
A 2.00 kg is released on a 53.1degree incline, 4.0 m from a long spring with force constant 120 N/m that is attached at the bottom of the incline. The coefficients of friction between the package and the incline are static friction constant = 0.40, and kinetic friction...
