Answer:
-1.8 kJ
Step-by-step explanation:
Given
- Displacement = 40 meters
- Force against = 45 N
Solving
- W = F x S
- W = - 45 x 40
- W = -1800 J = -1.8 kJ
Answer:
2250 J
Step-by-step explanation:
Work done is given by the formula :
work done = force × distance
Substituting values given gives us:
Work done = 45 × 40
Work done = 2250 J
