Question

1. Calculate a typical Reynolds number which would characterize the motion of a pendu- m subject to air drag. Use an average velocity for a one meter pendulum and a 30° amplitude. Take the density of air at room tem perature to be 1.205 × 10-3 gm/cm3 The radius of the pendulum bob is 2.0 cm. (You may use the equation for the period of a pendulum for small angles to calculate lu the approximate period.)
