The squid, weighing $5\mathrm{.}00$ kg$,$ ejects $0\mathrm{.}250$ kg of water at a speed of

$10\mathrm{.}0$ m$/$s relative to its body. This quick burst of water helps the squid move, but

its motion is slowed by the water's resistance $($a frictional force of $5\mathrm{.}00$ N$).$

Determine

i$.$ The recoil velocity of the squid if the ejection is done at $0\mathrm{.}100$s

$[6$ points$]$

ii$.$ Energy lost to work done against friction.
