A bit off-topic, but I just googled some IIT-JEE questions and found the following:
A large number of bullets are fired in all directions with same speed u. What is the maximum area on the ground on which these bullets will spread.
The provided answers all depend only on u, pi, and g.
How can this be possible? Obviously, if I fire the gun from a tower, this area will be larger than when I fire it from the ground, and thus also depends on the height above ground of the gun.
