Final answer:
To convert feet-pounds to joules, one would use the conversion factor where 1 pound-force equals 4.448 Newtons and multiply by the distance in meters. The question lacks specific values, but the conversion for 1 foot-pound is approximately 1.356 Joules.
Step-by-step explanation:
The question asks to convert a quantity from feet-pounds to joules. In physics, energy or work can be expressed in various units, including joules (J). To convert from feet-pounds to joules, we use the conversion factor of 1 pound-force (lbf) being equal to 4.448 Newtons (N), and knowing that work (W) is equal to force (F) multiplied by distance (D): W = F × D.
However, the question seems incomplete as we need to know the specific amount of force in pounds and distance in feet to calculate the work done in joules. But it is usually sufficient to remember that the conversion factor between foot-pounds and joules is based on the above relationship, which includes the need to convert feet to meters.
For example, the work done by lifting a 1-pound weight for 1 foot would result in 1 foot-pound of energy. To convert this to joules:
1 foot = 0.3048 meters
1 pound-force = 4.448 Newtons
Therefore, 1 foot-pound = 4.448 N × 0.3048 m ≈ 1.356 Joules.
