Find the block's speed v as a fraction of its initial speed when it has compressed the spring only $39\mathrm{.}1\%$ of the maximum distance. Fill in the missing factor below.

$[$Hint: Start by solving the "full compression'$\text{'}$ problem to find the spring constant. Then use conservation of energy to solve the partial compression'$\text{'}$ problem.$]$
