Question

a hamster in a ball begins its journey 10 feet to the left of a refrigerator, travels 20 feet to the right of the refrigerator, and ends its journey directly in front of the refrigerator. if negative values are assigned to positions to the left of its starting position and positive values are assigned to positions to the right of its starting position, what is the displacement of the hamster? (1 point) o 10 feet o -20 feet o 0 feet o 5 feet

Explanation:

Step1: Define starting and ending points

Let the starting - point be the reference point (0). The hamster starts 10 feet to the left of the refrigerator. Then it moves 20 feet to the right.

Step2: Calculate displacement

Displacement is the change in position from the starting - point to the ending - point. The starting position is considered 0. It moves 20 feet to the right. So the displacement $d=20 - 10=10$ feet.

Answer:

10 feet
