Question

The average acceleration in one time period in a simple harmonic motion is
(a) Aω²
(b) Aω²/2
(c) $A{\omega }^2/\sqrt{2}$
(d) zero

Answer 1

(d) zero

The acceleration changes its direction (to opposite direction) after every half oscillation. Thus, net acceleration is given as,
Aω² + ( -Aω²) = 0
