Part A

The $1\mathrm{.}9-kg$ block slides along a smooth plane and strikes a nonlinear spring with a

speed of $v=3\frac{m}{s}.$ The spring is termed "nonlinear" because it has a resistance of

$F_s=k{s}^2,$ where $k=600\frac{N}{m^2}.($Figure $1)$

Determine the speed of the block after it has compressed the spring $s=0\mathrm{.}2m.$

Express your answer to three significant figures and include the appropriate units.Ano :$-$
