What is the energy of a 15 pounds 2x4 traveling at 100 mph and how does it compare to a high power rifle bullet with an energy of 2339 ft-lbf?
The formula for kinetic energy is KE=1/2(mass)(velocity)^2, therefore 15 lbs travelling at 100 MPH has a kinetic energy of 5,012 ft lbs or more than twice that of the bullet! To get the answer you have to convert 15 lbs to mass by dividing by the gravitational constant (32.2 Ft/sec^2) and converting 100MPH to ft/sec. 15x(100x1.467)^2/(2x32.2)=5,012

What is kinetic energy of 124 grain 9mm bullet?
Conversions first. 124 grains (1 gram/15.43 grains)(1 kilogram/1000 grams) = 0.008036 kg ==============
How many FPS does 1000 Foot-Pounds translate to?
That is sort of like asking how many miles per hour does 100 horsepower equal. Ft lbs is energy, and FPS is speed. There IS a formula to calculate the energy (in foot lbs) of a bullet, but to use that, you need to know SPEED in FPS, and WEIGHT (in grains) of the bullet. A 40 grain bullet at 1000 fps is pretty weak. A 400 gr bullet at 1000 fps can drop a moose.
Which bullet is more powerful the 9mm or the 40 cal?
All else being equal, the one that has more foot pounds of energy.
How is foot pounds of energy measured for bullet impact?
It can be projected by using the formula E= MV2 divided by 450400. E is the energy in foot lbs M is mass of bullet in grains V2 is velocity in feet per second, squared. It can also be directly measured by taking a known weight, shooting it, and measuring the movement of the weight. This is known as a ballistic pendulum, and is not often used today.
How much pounds you have to wei gh to be bullet proof?
500 pounds
What is the force of an average bullet?
The force of an average bullet can vary depending on its caliber and velocity. Generally, bullets can exert thousands to tens of thousands of pounds of force upon impact with a target due to their high speed and energy.

How do you compare 1 and a quarter pounds in kilograms?
1.25 pounds = 0.57 (0.566990462) kilograms.
Convert a 260 grain bullet to lbs?
260 grains is equal to 0.037 pounds.
Is 1600 bigger or smaller than 10lb?
You can't compare that. You can compare pounds with pounds; or pure numbers with pure numbers.
