A body is projected horizontally from the top of abuilding of height h

1.	A body is projected horizontally from the top of abuilding of height h. Velocity of projection is u. Find
Answer» SOLUTION :u=initial velocity at the point A [Fig.2.90]. So, u=horizontal component of initial velocity , 0= vertical component of initial velocity. The horizontal component ,u= CONSTANT , since there is no ACCELERATION in that direction . But the vertical motion is under a constant acceleration g, the acceleration DUE to gravity. Let B be the point where the body strikesthe ground . The correspondingvertical motionis through the distance AO =h.
