- A. 50 J
- B. 15 J
- C. 5 J
- D. 10 J
Answer
50 J
Explanation
Work done is calculated using the formula W = F x s, where W is work done, F is force, and s is distance. Here, W = 10 N x 5 m = 50 J.
Common mistake
Proportional Reasoning in Work Done
Students often assume that if one braking force is twice another, the work done will also be twice, without considering the distance over which the force is applied.
To fix this, remember that work done is calculated as the product of force and distance. Ensure to compare both the force and the distance when applying proportional reasoning.
