In the figure below the spring (k = 75 n/m) has an equilibrium length of 1.00 m. the spring is compressed to a length of 0.50 m and a mass of 2.0 kg is placed at its free end on a frictionless slope. the spring is then released. (a) if the mass is not attached to the spring, how far up the slope will the mass move before coming to rest? (b) if the mass is attached to the spring, how far up the slope will the mass move before coming to rest? (c) suppose now that the has a coefficient of kinetic friction uk. if the block, ttached to the spring, is observed to stop just as it reaches the spring's equilibrium position, what is the coefficient of friction uk.?
