In Exercises 4-11, we consider the damped pendulum system de dt ap dt sine -v, m where b is the damping coefficient, m is the mass of the bob, I is the length of the arm, and g is the acceleration of gravity (g 9.8 m/s²).

Solve both parts properly

6. Suppose we have a pendulum clock that uses only a slightly damped pendulum to
keep time. The clock "ticks" each time the pendulum arm crosses e = 0.
(a) As the clock "winds down" (so the amplitude of the swings decreases), does
the clock run slower or faster?
(b) If the initial push of the pendulum is large so that the pendulum swings very
close to the vertical, will the clock run too fast or too slow?
