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

A stream of particles each of mass m moving with velocity v with number of particles per unit volume n strike against a wall at an angle theta to the normal elastically. Find the pressure exerted by the exerted by the stream on the wall.

A ball of mass 500 gram strikes a wall with a velocity of 80 m/s and rebounds with the same velocity. If the tme of contact is 1/30 sec, then the force exerted by the ball on the wall is
