A first stone is dropped from the roof of the building. 2s later a second stone is thrown straight down with an initial speed of 30 m/s. It is observed that both stones strike the ground at the same time. Determine the taken for the stones to strike the ground and the height of the roof from the ground.
As both the stones strikes the ground at the same time but first ball dropped has free fall under gravity and the second ball is thrown with some acceleration .
Calculation for time taken to hit the ground and height of roof is shown below.

A ball is thrown straight up from the edge of the roof of a building of height 60.0m. A second ball is dropped from the roof 2s later. What must be the initial speed of the first ball if both are to hit the ground at the same time?
A stone is dropped from the roof a high building a second stone is dropped. A second stone is dropped1.42s later. How far apart are the stones when the second one has reached a speed of 1.43 m/s? d=??m
