Please note that the max value is correct, I just need the minimum value. Thanks!

Problem $11\mathrm{.}108-$ Projectile with a given direction, find magnitude of initial velocity$($range$)$

A tennis player serves the ball at a height $h=3\mathrm{.}130m$ with an initial velocity of $5\frac{m}{s}.is$ given $as$

$\frac{m}{s}.$ for which the ball will land $in$ the service area that extends $to6\mathrm{.}4m$ beyond the net.

The range $of$ values $ofis$ given $as$

$\frac{m}{s}.atan$ angle $of5$ with the horizontal.

Determine the range $of$ for which the ball will land $in$ the service area that extends $to6\mathrm{.}4m$ beyond the net.

The range $of$ values $ofis$ given $as$

$\frac{m}{s}.$
