A 150 N/m, 5 m spring on a 26 degree incline is compressed 2.3 m and a 5 kg block is placed on it. If we neglect friction, how far up the incline from where it starts will the block travel? How fast will it be traveling when it is 0.2 m up the incline from where it starts?

IN this, you need to relate height gained to distance along the slope. sin26=h/distance
h=distance*sin26=.2*sin26
FinalKE=initialPE-mg*.2sin26
where intial PE is 1/2 k * 2.3^2
h=distance*sin26=.2*sin26
FinalKE=initialPE-mg*.2sin26
where intial PE is 1/2 k * 2.3^2
