A block of mass `m=0.14kg` is moving with velocity `v_0` towards a mass less unstretched spring of force constant `K=10Nm^-1`. Coefficient of friction between the block and the ground is `mu=1//2`.

Find the maximum value of compression in the spring (in cm), so that after pressing the spring the block does not return back but stops there permanently.

The correct Answer is:
`(7)`
Let compression in the spring be x.

`flgekximplies(1//2)xx0.14xx10gt10x`
`impliesxle0.07m=7cm`
