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 `5times10^(-4)m^(2)` .If the force exerted by water jet on the wall is `n times10^(2)N` assuming the water is brought to rest there,find the value of n .

A horizontal jet of water coming out of a pipe of area of cross-section 20cm^(2) hits a vertical wall with a velocity of 10ms^(-1) and rebounds with the same speed. The force exerted by water on the wall is .

A ball of mass 250 g moving with 20 m/s strikes a vertical wall and rebounds along the same line with a velocity of 15 m/s. If the time of contact is 0.1 s, the force exerted by the wall on the ball is

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.

A body of mass 3 kg moving with velocity 10 m/s hits a wall at an angle of 60^(@) and returns at the same angle. The impact time was 0.2 s. Calculate the force exerted on the wall.

A stream of water flowing horizontal with a speed of 15 ms^(-1) gushes out of tube of cross sectional area 10^(2) m^(2) and hits at a vertical wall nearby . What is the force exerted by the impact of water, assuming that water rebounds with the same speed.

A body is projected horizontally from the top of a tower with a velocity of 20m/s .After what time the vertical component of velocity is four times the horizontal component of velocity (g=10m/s^(2))

Water jet issues water from a nozzle of 2 cm^(2) cross-section with velocity 30 cm/s and strikes a plane surface placed at right angles to the jet. The force exerted on the plane is

A stream of water flowing horizontally with a speed of 15 ms^(-1) pushes out of a tube of cross sectional area 10^(-2)m^(2) and hits a vertical wall near by what is the force exerted on the wall by the impact of water assuming.that it does not rebound? (Density of water =1000 kg m^(3) )

A stream of water flowing horizontally with a speed of 15 m/s gushes out of a tube of cross sectional area 10^(-2)m^(2) and hits at a vertical wall and after collision falls dead. The force exerted on the wall by the impact of water is
