A ball of mass 0.1 kg strikes a wall normally with a speed of 30 m s ^( - 1 ) and rebounds with a speed of 20 ms ^( - 1 ) . The impulse of the force exerted by the wall on the ball is

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 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 . (take density of water =1000kg/ 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
