Now if the projectile's impulsive force had been correctly calculated, it would attain this point without speed, having lost all trace of weight, as well as all the objects within it. What would happen then? Three hypotheses presented themselves.
Well, my friends, let us be content with the moon for to-day. There, at least, we shall cut a great figure! Later on we shall see if we will go to the sun, where you can't drink without a crane to lift the glass to your mouth." Barbicane had now no fear, if not about the issue of the journey, at least about the projectile's force of impulsion. Its own speed would carry it beyond the neutral line.
Barbicane, desirous of obtaining some notion of the effect of the shock at the moment of the projectile's departure, had procured a 38-inch mortar from the arsenal of Pensacola. He had this placed on the bank of Hillisborough Roads, in order that the shell might fall back into the sea, and the shock be thereby destroyed.
To Captain Nicholl's maintaining that the projectile would smash like glass, Michel replied that he would break their fall by means of rockets properly placed. Thus, powerful fireworks, taking their starting-point from the base and bursting outside, could, by producing a recoil, check to a certain degree the projectile's speed.
Barbicane had no means of estimating the projectile's speed, but reasoning showed that it must uniformly decrease, according to the laws of mechanical reasoning. Having admitted that the projectile was describing an orbit around the moon, this orbit must necessarily be elliptical; science proves that it must be so. No motive body circulating round an attracting body fails in this law.
"Regarding question No. 6, 'What place will the moon occupy In the heavens at the moment of the projectile's departure?
The travelers' sleep was rendered more peaceful by the projectile's excessive speed, for it seemed absolutely motionless. Not a motion betrayed its onward course through space. The rate of progress, however rapid it might be, cannot produce any sensible effect on the human frame when it takes place in a vacuum, or when the mass of air circulates with the body which is carried with it.
"Regarding question No. 3, 'What would be the duration of the projectile's transit to which a sufficient initial speed has been given, and consequently at what moment should it be hurled so as to reach the moon at a particular point?
It was impossible to ascertain. The thickness of the projectile's walls prevented any interior noise from reaching the outside. On the 20th of November, at six o'clock precisely, the plate was removed; the friends of J.T. Maston were rather uneasy. But they were promptly reassured by hearing a joyful voice shouting a formidable hurrah!
"But that's exactly what we want to do ourselves, friend Ardan," said Barbican, endeavoring to give an example of calmness to the impatient M'Nicholl; "the only trouble is that we have not the means to do it." "Can't we modify the Projectile's movement?" "No." "Nor diminish its velocity?" "No." "Not even by lightening it, as a heavily laden ship is lightened, by throwing cargo overboard?"
