NEET Physics Work-Energy Theorem MCQ Question
Consider a diagram illustrating a cyclist coming to a skidding stop over a distance of 10 m. The force applied by the road is 200 N and acts directly opposite to the direction of motion. What is the work done by the road on the cycle?
-2000 J
2000 J
0 J
1000 J
Correct Answer
Detailed Explanation
The work done by the road is calculated using W = Fd cos θ. With θ = 180°, the work done is W = 200 × 10 × cos(π) = -2000 J, showing negative work that stops the cycle.
