(Linear momentum) A horizontal air jet having a velocity of $$55.4\mathrm{m}/\mathrm{s}$$ and a diameter of $$20\mathrm{mm}$$ strikes the inside surface of a hollow hemisphere as indicated in the figure below. How large is the horizontal anchoring force needed to hold the hemisphere in place? The magnitude of velocity of the air remains constant. $$\mathrm{N}$$
