spirng question?!?! A block of mass 1.7kg is in a spring (k= 250N/m^2) compressed 3.0m. The spring is frictionless, but friction exists past the equilibrium point. u_s=.44 & u_k=.32 The track goes horizontally a distance 25m and then up a ramp of angles 45 degrees to the horizontal. a. What is the initial mechanical …
