A pendulum is swinging back and forth. Consider locations A - E. A plot of velocity as a function of time is shown. A + velocity represents a pendulum bob moving to the right; a - velocity represents a leftward motion.
Graphical Analysis
Consider the red-shaded section. This section represents the pendulum bob moving from locations …
