Problem 6: A mass at the end of a spring describes SHM with a period of 0.04 s. Find the acceleration when the displacement is 4 cm.

Answer

Given data   Time period = T = 0.04 s                 displacement = x = 4cm = 0.04 m

Required          Acceleration of the spring = a =?

Formula

Put values in the above formula,

(Note: The acceleration has negative sign).
