To solve the problem of calculating the gain in potential energy of a bob swinging from a vertical position, we can follow these steps: ### Step 1: Understand the Physical Situation We have a bob of mass \( m = 2 \, \text{kg} \) hanging from a string of length \( L = 5 \, \text{m} \). The bob swings to one side, making an angle of \( 60^\circ \) with the vertical. ### Step 2: Determine the Height Change When the bob swings to the side, it rises to a certain height. To find this height, we can use trigonometry. ...
