7. A small, private airplane is carrying three passengers to an island. The plane is 0.9 km in the air. If the potential energy of the plane and its three passengers is 48,510,000 J, what is the combined mass of the plane and its passengers? Round your answer to the tenth place. 8. If the plane from question 7 has a mass of 5,275 kg, and all three passengers have the same mass, what is the mass of each passenger?

this is poiselle's equation from fluid mechanic in physics. mech eng

no. dot product   =0 when vecs at right angles

i think the answer would be reserve.
