# Simple Pendulum Help

XuFyaN
in this simple pendulum there are 3 points A,B,C , at point A the displacement is 0 , at point B the displacement is maximum and at point C what is the displacement??
also
When the Pendulum starts from maximum Displacement i.e point B , the velocity at point B would be 0, and at point A the velocity would be maximum , what would be the displacement at point C ?
also
When the pendulum is at point B (maximum displacement) will the acceleration is maximum ??

can anyone explain its graphical representation ?
Velocity vs time, Acceleration vs time.
