Which most simplified form of the law of conservation of energy describes the motion of the block when it slides from the top of the table to the bottom of the ramp?
1/2mv^2i+mghi+Wnc=1/2mv^2f+mghf
1/2mv^2i+1/2kx^2i=1/2mv^2f+1/2kx^2f
1/2mv^2i+mghi=mghf+1/2kx^2f
1/2mv^2i+mghi=1/2mv^2f+mghf
1/2mv^2i+mghi+1/2kx^2i+Wnc=1/2mv^2f+mghf+1/2kx^2f
