Question

A pendulum is oscillating between points a,b and



c. Acceleration of bob at points a or c is

Answer 1

acceleration of bob is at point a as it goes from point a having max potential energy and zero kinetic energy to point b at the center having max. kinetic energy and zero potential energy to point c having max potential energy and zero kinetic energy this continues for short time then due to friction from the air stopes oscillating.
