Text Solution

AI Generated Solution

To find the coefficient of friction for the train being drawn by the engine, we can follow these steps: ### Step 1: Convert the given values to appropriate units 1. **Convert the velocity from km/h to m/s**: \[ \text{Velocity} = 36 \text{ km/h} = \frac{36 \times 1000}{3600} = 10 \text{ m/s} \] ...
