A pendulum of unknown mass is suspended from a platform and swings as shown in the animation (assume negligible loss of energy due to air resistance; position is shown in meters and time is in seconds).
Determine the speed of the pendulum bob when it is at its lowest point. Start
0.63 m/s.
See Giancoli-PA: 6-5, Giancoli-SE: 8-1.
