v = Vi + 9.8 t
12 = 0 + 9.8 t
t = 1.22 seconds that the second stone is in the air so the first one is in the air for 2.22 seconds
------------------------
First stone:
d = (1/2) 9.8 (2.22)^2
= 24.1 meters
Second stone:
d = (1/2) 9.8 (1.22)^2
= 7.3 meters
---------------------------
so
24.1 - 7.3 = 16.8 meters difference
A stone is dropped from the roof of a high building. A second stone is dropped 1.00s laterHow far apart are the stones when the second one has reached a speed of 12.0m/s ?
