2. (20) A spring in figure 2a rest on a 30 degree incline, Itsuncompressed length is 0.8m. A 2.0 kg mass is placed on the inclineand pushed down so that the spring is compressed 0.6 m from it'sequilibrium position. If the coefficient of kinetic frictionbetween the mass and the incline is 0.2 and the block moves up theincline 1.0 m after the spring is released determine the springconstant k.
