A jet of water with cross section of `6 cm^(2)` strikes a wall at an angle of `60^(@)` to the normal and rebounds elastically from the wall without losing energy. If the velocity of the water in the jet is `12 m//s`, the force acting on the wall is

A jet water, whose cross section is A strikes a wall making an angle theta with normal and elastically rebounds. The velocity of water of density rho is v . Force exerted on wall is :-

A particle of mass M strikes a wall at an angle of incidence 60^(@) with velocity V elastically Then the change in momentum is

A 0.5 kg ball moving with a speed of 12 m//s strikes a hard wall at an angle of 30^(@) with the wall. It is reflected with the same speed and at the same angle . If the ball is in contact with the wall for 0.25 s , the average force acting on the wall is
