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

a
AKM
b
A2KM
c
A2KM
d
AMK

detailed solution

Correct option is C

vo=ωA (−j^) vI=ωA (−i^) Velocity of object wrt image : vOI=vo−vi = ωAi^−ωAj^ υmax=υ2=2ωA=2AKM
