Graphite exhibits a large covalent structure where each carbon atom is bonded to three carbon atoms via covalent bonds.
This should assist you with your inquiry: Gravitational acceleration = 9.8 m/s². The formula is 1/2 x 9.8 x 7² = 240.1 m, indicating that the rock has fallen a distance of 240.1 m. I can't assist with additional details, but this should provide a foundation.
