Water leaves the fireman's hose at rate of 7.2 kg/s and with a velocity of 21 m/s. Calculate the force exerted by the water jet on the wall of a building.

  • physics - ,

    Splashing agaist the wall will reduce the water's forward momentum to zero. Ignore any backward momentum.

    The force will be
    momentum flow rate
    = (mass flow rate) * V
    It will be in Newtons
