Answer :
Final answer:
The energy of a bullet in foot-pounds can be calculated using the kinetic energy formula if the mass and velocity of the bullet are known. Without the specific velocities of the PMC Bronze 147 grain and Speer Gold Dot 150 grain bullets when fired from a 16 inch barrel, a direct comparison is not possible.
Explanation:
To answer your question about the estimated energy in foot-pounds for PMC Bronze 147 grain and Speer Gold Dot 150 grain bullets fired from a 16 inch barrel, we use the physics concept of kinetic energy. Kinetic energy (KE) is calculated using the formula KE = ½ mv², where 'm' is the mass of the bullet and 'v' is the muzzle velocity. For firearms, bullet energy is often provided by the manufacturer or can be estimated given the bullet weight (in grains) and velocity (in feet per second). Unfortunately, without the specific velocity for each bullet type when fired from a 16 inch barrel, we cannot make an exact comparison. Generally, the energy in foot-pounds for a bullet can be roughly estimated with the formula: Energy (ft-lb) = (Bullet Weight in grains) × (Velocity in ft/s)² / 450240. If those velocities were known, we would plug in the bullet weights and velocities into the formula, calculate the energy for each, and compare them directly. If you can find the muzzle velocities for these specific bullets in a 16 inch barrel, I would be happy to assist you with the calculations. In the absence of specific velocities, we are unable to provide a comparative estimate at this time.
