WAEC Physics
During a training session, two footballers pass a ball repeatedly between each other. The 'to and fro' motion of the ball is not simple harmonic because
I. acceleration of the ball is not directed towards a fixed point
II. restoring force a fixed point
III. acceleration of the ball is not directly proportional to the displacement from a fixed point.
Which of the statements above are correct?
