$10\mathrm{.}13$R $($Hydraulic jump$)$ At the bottom of a water ride

in an amusement park, the water in the rectangular channel has

a depth of $1\mathrm{.}2ft$ and a velocity of $15\mathrm{.}6f\frac{t}{s}.$ Determine the height

of the "standing wave" $($a hydraulic jump$)$ that the boat passes

through for its final "splash."
