- Editor's Notes
- "A gentleman in this city has I think been quoting you incorrectly with reference to a scientifica question, & I take the liberty of referring the matter to you. The question is, "Suppose a railway train, runnin gon a straight track with a uniform velocity of 60 miles per hour; it has one board a cannon capable of throwing a ball with the velocity of 60 miles per hour; the cannon is discharged in same direction as train is running; what is the true velocity of the ball?" Our friend claims that it would have no greater velocity than if the cannon had been fired from the ground, giving you as his aughority. As he is a man of some consequence, quite a number are disposed to believe him. Please explain in a few words on back of this & oblige" A.C. Jeunis TAE marg:: "Never made any such decision. The cannon ball would of course have the velocity of both the train & the ball ie 120 m per hour"] [PUBLIC REFERENCE INQUIRY]
