Horizontal distance travelled by cannon ball is directly proportional to the muzzle velocity, if fired at 45 degree projection angle.
Henry was wondering how cannons were used before in the war. He was experimenting with two cannons in testing zone to obeserve the distance covered by cannon balls. Two cannons shot two identical cannon balls. The cannon ball that covered less distance have muzzle velocity of 241 meter/seconds.
Q: Is it true that "Muzzle velocity of the other cannon ball could be 234 meter/second."
