सरल आवर्त गति (SHM) कर रहे एक कण द्वारा एक पूर्ण आवर्तकाल में तय की गई दूरी कितनी होती है (जहाँ आयाम = A)?

A particle undergoes Simple Harmonic Motion (SHM) with angular frequency ω = 0.5 rad/s and amplitude A = 5 cm. Find the magnitude of acceleration when its displacement from the mean position is x = 4 cm.

A particle moves along the x-axis in simple harmonic motion such that its speed varies as v2 = 100 - x2. Determine the time period T of oscillation.
