Answer:
The work done by the particle during its displacement of 12 m is 13 J.
Explanation:
Given: Force = F
displacement = d (values as shown in attached file)
To find: The work done during the given displacement.
Solution: #For work done, we know that:
W = Area of force-displacement graph
So, we find the area of force-displacement graph for the numerical values of work done.
Area = area of rectangle + area of triangle
[Refer to the attached image]
Area = 4 × 2 + 1/2 × 2 × 5
Area = 8 + 5
Area = 13 J = Work done
Hence, the work done by the particle during its displacement of 12 m is 13 J.
