AB is a man of height 2m and M is a mirror of length 0.5m and mass 0.1 kg. Initially top of mirror M and A are at the same level and the M starts falling freely always remaining vertical. If the level of the eyes of the manis 1.5 cm below his head. A, find the time after which the man sees the reflection of his feet.
