$6-30$E A $3-$in$-$diameter horizontal jet of water, with speed $\backslash (140\backslash$mathrm$\{$ft$\}/\backslash$mathrm$\{$s$\}\backslash ),$ strikes a bent plate, which deflects the water by $\backslash (135^\{\backslash$circ$\}\backslash )$ from its original direction. How much force is required to hold the plate against the water stream and what is its direction? Disregard frictional and gravitational effects.
