Horizontal distance travelled by cannon ball is directly proportional to the muzzle velocity, if fired at 45 degree projection angle.
Context: Finn 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 more distance have muzzle velocity of 164 meter/seconds.
Question: "Muzzle velocity of the other cannon ball could be 155 meter/second." -- Is this statement true?
