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).
Use conservation of energy to determine the speed of the pendulum bob when it is at its lowest
point. Start
1.5 m/s.
See Giancoli-PA: 6-5, Giancoli-SE: 8-1.
