Consider a pendulum, of length l and a bob of mass mat its end, moving through a lubricated oil with decreasing 0. The massive bob undergoes small oscillations, but the oil retards the bob's motion with a resistive force proportional to the speed with Fres = (2m ) (10). The bob is initially is pulled back at t=0 with 0 0, and 0 = 0, = 0. Find the Consider a pendulum, of length l and a bob of mass mat its end, moving through a lubricated oil with decreasing 0.
