Simple harmonic motion

Classical Mechanics Level 2

An insect of negligible mass is sitting on a block of mass M M , tied with a spring of force constant k k . The block performs a simple harmonic motion with amplitude A A in front of a plane mirror placed as shown in the figure. The maximum speed of insect relative to its image will be-

A 3 2 k M A \dfrac{\sqrt{3}}{2} \sqrt{ \dfrac{k}{M} } A 3 k M A \sqrt{3} \sqrt{ \dfrac{k}{M} } A k M A \sqrt{ \dfrac{k}{M} } A M k A \sqrt{ \dfrac{M}{k} }
