A 23-cm-diameter horizontal water jet with a speed of Vj = 20 m/s relative to the ground is deflected by a 40° cone moving to the left at Vc = 10 m/s. Determine the external force, F, needed to maintain the motion of the cone. Disregard the gravity and surface shear effects, and assume that the cross-sectional area of the water jet normal to the direction of motion remains constant throughout the flow. Take the density of water to be 1000 kg/m3.
The external force, F, needed to maintain the motion of the cone is N.

a 50-mm-diameter jet of water impacts a vane at a
velocity of 20 m/s as shown in Figure 4.78. The vane has a mass of
90 kg, and it deflects the jet through a 55° angle. The vane is
constrained to move in the direction of the incoming jet, and there
is no force opposing the motion of the vane. Determine the
acceleration of the vane when it was first released. Assume water
