A Hose Directs A Horizontal Jet Of Water Moving With A Velocity Of 20m S On To A

A hose directs a horizontal jet of water, moving with a velocity of 20m/s, on to a vertical wall. The

cross-sectional area of the jet is 5 x 10-4m2

. If the density of water is 1000kgm-3

, calculate the force on a

wall assuming the water is brought to rest there
