Given data:
Initial velocity of the rock;

Launch angle;

The maximum height the rock will go is given as,

Here, g is the acceleration due to gravity.
Substituting all known values,

Therefore, the rock will attain a maximum height of 13775.51 m.
The horizontal range is given as,

Substituting all known values,

Therefore, the rock will land 31813.18 m away from the launch site.
