A spring (k= 75N/m) has an equilibrium length of 1.00 . Thespring is compressed to a length of 0.50 and a mass of 2.0 kg isplaced at its free end on a frictionless slope which makes an angleof 41 degrees with respect to the horizontal. The spring is thenreleased.
Part A
If the mass is not attached to the spring, how far up the slopewill the mass move before coming to rest?
=
Part B
If the mass is attached to the spring, how far up the slope willthe mass move before coming to rest?
=
Part C
Now the incline has a coefficient of kinetic friction "μk". If theblock, attached to the spring, is observed to stop just asitreaches the spring's equilibrium position, what is thecoefficient of friction "μk"?
