Webto get to the answer /real answer one must find out the time taken by the body sent upward to meet the top body (as if the body was not dropped) so if you divide the height 200m by the velocity 50m/s then one gets 4 sec. if you do all equations as done by another responder for accelerated motion ultimately you will get the same answer. WebAt what height from the ground will the stone meet? Solution Let distance measured from bottom be s1 and distance from top be s2. s2 = 1 2 g t2 s1 = ut - 1 2 g t2 100 = s1 + s2 100 = ut = 50 t t = 2 secs Distance from top = 1 2 g t2 = 19.62 m Height = 100 - 19.62 = 80.38 m.
