A hummingbird hovers by exerting a downward force on the air equal, on average, to its weight. By Newton's third law, the air exerts an upward force of the same magnitude on the bird's wings. Find the average mechanical power (in W) delivered by a 3.60 g hummingbird while hovering if its wings beat 75.0 times per second through a stroke 3.98 cm long. HINT To find the average power per stroke, calculate the work done each stroke and divide by the time per stroke. Click the hint button again to remove this hint.
