Energy in SHM

The amplitude of a particle executing SHM is $3$ cm. The displacement at which its kinetic energy will be $25\%$ more than the potential energy is (in cm)

Show answer and solution

Answer: (b)

$KE = 1.25\,PE \Rightarrow A^2 - x^2 = 1.25x^2$
$2.25x^2 = A^2 = 9 \Rightarrow x^2 = 4$
$x = 2\text{ cm}$
So the answer is (b) 2.
