A pendulum is swinging back and forth with a mass on its end. At the instant when the pendulum reaches its lowest point, how would you describe the speed and the magnitude of the acceleration of the mass? A. Its speed is at a minimum and the acceleration is at a maximum. B. Its speed is at a minimum and the acceleration is at a minimum. C. Its speed is at a maximum and the acceleration is at a maximum. D. Its speed is at a maximum and the acceleration is at a minimum.

This means that the motion is periodic and the restoring force is proportional to the displacement from the equilibrium position. Show more…

A pendulum, consisting of a bob of mass $M$ on a cord of length $L$, is interrupted in its swing by a peg a distance $d$ below its point of suspension. (a) If the bob is to travel in a full circle of radius $(L-d)$ around the peg, what is the minimum possible speed it can have at the lowest point in its motion, just before it starts to go around? Ignore any decrease in the length of the string due to the peg's circumference. (b) From what minimum angle $\theta$ must the pendulum be released so that the bob attains the speed calculated in (a)?
