A spring (k=75 N/m) has an equilibrium length of 1.00 m. Thespring is compressed to a length of 0.50m and a mass of 2.0kg isplaced at its free end on a frictionless slope which makes an angleof 41 degrees with respect to the horizontal. The spring is thenreleased.
a) If the mass is not attached to the spring, how far up theslope will the mass move before coming to rest?
b) If the mass is attached to the spring, how far up the slopewill the mass move before coming to rest?
c) Now the incline has a coefficient of kinetic frictionμk . If the block, attached to the spring, is observedto stop just as it reaches the spring's equilibrium position, whatis the coefficient of friction μk?
