A small fly of mass 0.26 is caught in a spider's web. The web vibrates predominately with a frequency of 4.6 .
a)What is the value of the effective spring stiffness constant for the web?
b.)At what frequency would you expect the web to vibrate if an insect of mass 0.52 were trapped?
2PI f= sqrt (k/m)
solve for k.
