To solve the problem of the work done by the cycle on the road, we can follow these steps: ### Step 1: Understand the scenario The bicyclist comes to a skidding stop, which means that the bicycle is initially in motion and then comes to a stop over a distance of 10 meters. The force acting on the bicycle due to the road is 200 N, and this force opposes the motion of the bicycle. ### Step 2: Identify the forces The force of 200 N is acting in the opposite direction to the motion of the bicycle. This force is responsible for stopping the bicycle. ...
