The work done in moving the chair from x = 2.4 to x = 4.1 ft using a force of F = 13 lbs is 29.98 J
<h3>What is work done? </h3>
This is simply defined as the product of force and distance moved in the direction of the force. Mathematically, it can be expressed as
Workdone (Wd) = force (F) × distance (d)
Wd = Fd
<h3>How to convert lb to N</h3>
1 lb = 4.45 N
Therefore,
13 lbs = 13 × 4.45
13 lbs = 57.85 N
<h3>How to determine the distance in m</h3>
- Initial distance = 2.4 ft
- Final distance = 4.1 ft
- Change in distance = 4.1 -2.4 = 1.7 ft
1 ft = 0.3048 m
Therefore,
1.7 ft = 1.7 × 0.3048
1.7 ft = 0.51816 m
<h3>How to determine the workdone</h3>
- Force (F) = 57.85 N
- Distance (d) = 0.51816 m
- Workdone (Wd) =?
Wd = Fd
Wd = 57.85 × 0.51816
Workdone = 29.98 J
Thus, the workdone in moving the chair is 29.98 J
