This would mean that the Initial Velocity (vertical) would be 0, as the bullet does not start with a vertical velocity. In this case, since the acceleration he is using is the vertical acceleration due to gravity, 32 feet/s/s, he should restrict all the other values he inserts to the vertical axis as well. When using this formula, the situation (meaning all the inserted variables and values) should be restricted to the axis on which the acceleration is acting. Second, Keith’s application of the formula Vf=Vi+AT is incorrect. Even if we are only considering pistols, this still ranges from 700 to over 2400 feet per second for normal pistols, with the average pistol hovering around 1000 feet per second. Furthermore 1000 fps is certainly not the limit for a firearm, as the M16 round travels at 3200 fps. The lowest velocity I have ever heard of for a firearm was 700 fps for a low-velocity large caliber pistol. I don’t know of any conventional firearm (post-1900) that travels at a mere 400 feet per second.

A few months later, we were lucky to talk with Adam about the Mythbusters, science education, and how he uses both experimentation and learning from mistakes in his work both on and off the show. Of course, we knew that we had to get Adam on the show. We first met Adam Savage (from the Mythbusters) at The Amaz!ng Meeting 7 last summer, where he gave a talk about the creative process and failure that comes with ‘making’.
