**MathMate**, Tuesday, August 24, 2010 at 2:28pmThe height y1 of the first object from the initial position, y0 with respect to time is given by the equation:

y1=ut-(1/2)gt²

Similarly, the height y2 of the second object is given by:

y2=-ut - (1/2)gt²

where

g=acceleration due to gravity, and

u=initial speed

The distance between the two objects is therefore given by y1-y2

=2ut

which is a linear function of time.

Make your choice of the answer and post it for checking if you wish.
