A pendulum that is used in your physics laboratory

Chapter , Problem 82

(choose chapter or problem)

A pendulum that is used in your physics laboratory experiment has a length of 75 cm and a compact bob with a mass equal to 15 g. To start the bob oscillating, you place a fan next to it that blows a horizontal stream of air on the bob. While the fan is on, the bob is in equilibrium when the pendulum is displaced by an angle of from the vertical. The speed of the air from the fan is You turn the fan off, and allow the pendulum to oscillate. (a) Assuming that the drag force due to the air is of the form predict the decay time constant for this pendulum. (b) How long will it take for the pendulums amplitude to reach
