During a training session two footballers pass ... - WAEC Physics 2018 Question
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 the
I. Acceleration of the ball is not directed towards a fixed point
II. Restoring force is not directed towards the centre
III. Acceleration of the ball is not directly proportional to the displacement from a fixed point
Which of the statements above are correct?
A
I and III only
B
I and II only
C
II and III only
D
I, II and III
correct option: a
In Simple Harmonic Motion, the body in motion must have acceleration in a direction opposite to the displacement and the acceleration is directly proportional to displacement and is directed towards its mean position.
