Question 11
Work, Energy and PowerFrom the diagram above, calculate the work done when the particle moves from x = 0m to x = 80m
- A.1200J
- B.2400J
- C.6000J
- D.7000J.
Show the answer and explanation
Answer: B (2400J)
Explanation
Work done is the area under the force–distance graph. From x = 0 to 80 m it is a triangle of base 80 m and height 60 N: ½ × 80 × 60 = 2400 J.
