It is better if you go by chapter and topic rather than by book , this way you get insight on the topic . Also to search on the net it is easier by chapter and topic . See if this helps.

The penny's speed relies upon upon how lots mass the international has "gravity"... Now as quickly because of fact the penny is dropped it is going to start to fall with a relentless acceleration relative to the mass the international the penny is falling to, has. speed = (acceleration) * 369.... or something like that. i'm to lazy to discover the precise "gravitational" pull of earth.
