Answer:
The amplitude of the wing tip's motion is 1.6 mm.
Explanation:
Given that,
Beat = 250 /s
Speed = 2.5 m/s
We need to calculate the amplitude of the wing tip's motion
Using the equation for the maximum velocity


Where,
v = speed
f = frequency
A = amplitude
Put the value into the formula



Hence, The amplitude of the wing tip's motion is 1.6 mm.
