To determine the displacement of the hamster, we need to analyze its starting and ending positions in relation to the refrigerator.
- The hamster starts 5 feet to the left of the refrigerator, which we can assign a position of -5 feet.
- It then travels 20 feet to the right, which means it moves from -5 feet to the right by 20 feet.
Starting from -5 feet and moving 20 feet to the right: \[ -5 + 20 = 15 \text{ feet} \] Thus, the hamster ends up at +15 feet, which is 15 feet to the right of the refrigerator.
Displacement is calculated as the difference between the final position and the initial position. Here, the initial position is -5 feet and the final position is +15 feet: \[ \text{Displacement} = \text{Final Position} - \text{Initial Position} = 15 - (-5) = 15 + 5 = 20 \text{ feet} \]
Therefore, the displacement of the hamster is 20 feet.
The correct answer from the options provided is: 20 feet
