Which one of the following differential equations correctly represents the displacement x(t)x(t) of a mass mm attached to an ideal spring of spring constant kk on a friction-less horizontal surface? (a) d2xdt2−km x=0\dfrac{d^{2}x}{dt^{2}}-\dfrac{k}{m}\,x=0 (b) d2xdt2+mk x=0\dfrac{d^{2}x}{dt^{2}}+\dfrac{m}{k}\,x=0 (c) d2xdt2+km x=0\dfrac{d^{2}x}{dt^{2}}+\dfrac{k}{m}\,x=0 (d) d2xdt2=−kx\dfrac{d^{2}x}{dt^{2}}=-k x
