Question

an obiect is dropped from top of tower 156.8m
high. Another object at same instant of time is project
with Velochy 78.1 m/sec vertically upward from
foot of tower, when and where will they meet?​

Answer 1

Since the hight of the building is
H=156.8
And the velocity of the throne object
V=78.1
The 2 objects come in contact with each other at half of the buildings hight(i.e)
In one second
Half ofH=156.8\2=78.1
As the range its thrown and the ball left from the hight is at same instant that must collide at half of building at exact one second of release

Hope it worked
