**drwls**, Saturday, March 29, 2008 at 3:40pmFrom the maximum height reached, you can determine the launch velocity

V = sqrt (2 g H) = 260 ft/s. Since the pieces at the ground arrive at the same time, they split in such a way that they acquire no vertical velocity components; otherwise one would go up and the other down. The time required for the pieces to fall after separating is T = sqrt (2*1051 ft/g) = 8.08 s

Since the the separation explosion occurred at the top of the trajectory and did not make the fall time different for the two pieces, the time to fall without the explosion would be the same as observed, 8.08 s. The info about how far away one piece landed is not needed.
