Helicopter Thrust During a rescue operation, a 5300-kg helicopter hovers above a fixed point. The helicopter blades send airdownward with a speed of 62 m/s. What mass of air must pass through the blades every second to produce enough thrust for the helicopter to hover?

The powerful downdraft from this helicopter’s blades creates a circular wave pattern in the water below. The thrust resulting from this downdraft is sufficient to support the weight of the helicopter. (Problem)
