A man hosing down his driveway hits the wall by mistake. Knowing that the velocity of the stream is 25 m/s and the cross-sectional area of the stream is 300 `mm^(2)`, determine the force exerted on the wall. Assume that streamstrikes wall horizontally and after striking the wall, stream comes to rest. Also find the pressure exerted on the wall by stream.
