a. F=kx find k
b. energy=1/2 k x^2
change units to N, meters.
This question has been blowing my mind, and my teacher is offering no help whatsoever.
Experiments performed on the wing of a hawkmoth (Manduca sexta) show that it deflects by a distance of = 4.9 mm when a force of magnitude = 3.2 mN is applied at the tip.
A: Treating the wing as an ideal spring, find the force constant of the wing.
B: Treating the wing as an ideal spring, find the energy stored in the wing when it is deflected.
What force must be applied to the tip of the wing to store twice the energy found in part (b)?
