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

A block of mass $m=2\mathrm{kg}$ is moving with velocity $v_0$ towards a massless unstretched spring of force constant $\mathrm{k}=10\mathrm{N}/\mathrm{m}$. Coefficient of friction between the block and the ground is $\mu =\frac{1}{5}$. Find maximum value of ${\mathrm{v}}_0$, so that after pressing the spring the block does not return back but stops there permanently.
