Magnitude of velocity of a body on reaching the point from which it was projected upwards is

detailed solution

Correct option is D

Velocity of body while reaching point of projection is same as at velocity projection in reverse directionwe know , V=u+at while projecting up a=-g time flight=t=2ug velocity on reaching point of projection =V=u+(-g)(2ug)                                                                     V=-u body on reaching point of projection will have same velocity as at projection but opposite in direction as we obtained negative in the solution
