1. Mass m moves along a track with the particular properties shown: an initial frictionless quarter-circle of radius r, and a segment of length d whose coefficient of kinetic friction changes linearly with position. The mass then collides with a spring, which compresses until the mass comes to a stop (no track friction). Assuming that the spring compresses with maximum distance xmax, find the spring constant k in terms of given quantities. * A m d Xmax D B k=o+1x/d (x=0, at B) C =0 1.
