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 ______ cm.
Numerical value type. Enter your answer.
Answer: 2
$K=1.25U$ and $K+U=E$, so $U=\dfrac{E}{2.25}$: $x^2=\dfrac{A^2}{2.25}\Rightarrow x=\dfrac{3}{1.5}=2$ cm.
