Physics - W.E.P. Question with Solution | TestHub

A sleeve of mass $\mathrm{m}=10\mathrm{kg}$ can slide on a straight vertical smooth rod. The sleeve is connected to a spring of spring constant $\mathrm{k}=1000\mathrm{N}/\mathrm{m}$, whose other end is connected to a fixed support as shown in figure. The sleeve is released when the spring is horizontal and relaxed. Find the speed in SI units of the sleeve when it descends a distance of 40 cm . (Use $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$ )
