Question

1. A small fly of mass 0.30g is caught in a spider's web. The web oscillates predominantly with a frequency of 4.5Hz .

Part A

What is the value of the effective spring stiffness constant k for the web?

Part B

At what frequency would you expect the web to oscillate if an insect of mass 0.60g were trapped?

2.

Part A

Derive a formula for the maximum speed vmax of a simple pendulum bob in terms of g, the length L, and the maximum angle of swing ?max.

3.

Part A

Suppose you pull a simple pendulum to one side by an angle of 5?, let go, and measure the period of oscillation that ensues. Then you stop the oscillation, pull the pendulum to an angle of 10?, and let go. The resulting oscillation will have a period about ________ the period of the first oscillation.
