Assuming an earth normal gravity, what would the initial launch velocity have to be, in order for an object to leap into the air, and take 15 seconds to come back to earth?
The book details that jumps involve jets and/or rockets, but this question does give an upper bound, if an extreme one: 241 feet per second (73 m/s, 160 mph) vertically, 341 feet per second (103 m/s, 225 mph) if leaping at a 45 deg angle for maximum distance. The distance leap will cover 2/3 of a mile (1.07 km), and maximum height in either case is 563 meters, 1856 feet.
This is Newtonian math with air resistance neglected as always. -- Jeff Wilson - [EMAIL PROTECTED] < http://www.io.com/~jwilson > _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
