suppose I have a horizontal problem where I have a spring attached to a wall, a body that moves toward it in some inital speed and the surface isn't smooth so I have friction along the surface towards the spring and also while the body contracts the spring. I'm asked what's the maximal contraction? I get 2 values for Xmax: one positive and the other negetive (also different in absolute value). One of them is 0.149 m and the other is -0.208. How can I know which one represents maximal contraction and which one represents maximal strechning?
this is a general question - never mind the specific values of k, mue(k), distance from spring at which body starts from with vo etc...
