The simple pendulum shown oscillates in the vertical plane (the plane of the figure) as
the pendulum cord is being steadily retracted through the opening at O with a constant
speed v. Consider the oscillations of the pendulum between positions O and ®, where
8, and 0, are the maximum swing angles of the pendulum at O and O, respectively. Let
L, and L, denote the lengths of the cord at 0 and ®, respectively, and let m denote the
L1
mass of the pendulum bob. Neglecting all forces except gravity and the tension in the
cord, determine the angular impulse relative to O provided to the pendulum bob in going
from 0 to 2.
