( 10 points) The velocity of water leaving a nozzle is $1.5\mathrm{m}/\mathrm{s}$ relative to the nozzle. The nozzle area is $0.010\mathrm{m}2$. If a flat plate is put in front of the nozzle, determine the horizontal force on the plate if the nozzle is moving towards right with a velocity of $3.5\mathrm{m}/\mathrm{s}$ and the flat plate is moving towards right with a velocity of $2.5\mathrm{m}/\mathrm{s}$ (density of water is $1000\mathrm{kg}/\mathrm{m}3$.). a. $62.5\mathrm{N}$ b. $2.5\mathrm{N}$ c. $2560\mathrm{N}$ d. none of them is correct. e. $422.5\mathrm{N}$
