...greater than that of 1 1 00 or 1 20O feet in a second, then the absolute quantity of the resistance in these greater velocities will be near three times...should be by a comparison with the smaller velocities. — Hence then it appears, that if a projectile begins to move with a velocity less than that of Iioo... | |
