An object moves with velocity v→0=10i^+j−2k in front of a plane mirror moving with velocity V→M=−5j^.Plane of the mirror is parallel o the xy plane with its reflecting surface facing the positive z axis. The velocity of the image is :

V→O/M=V→O−V→M=10i^ +6j^ -2k^ So VI/M→=10i^ +6j^+2k^ Therefore,VI→ =VM→+VI/M→ =10i^+j^+2k^
