Question

1. a car travels along a straight road for 15 kilometers north and then takes a turn and travels 10 kilometers south. determine the total distance traveled by the car and its displacement from the starting point. answer in si units.

Explanation:

Step1: Calculate total distance

The total distance is the sum of the distances of each part of the journey.
$d_{total}=15\ km + 10\ km=25\ km$

Step2: Calculate displacement

Displacement is the straight - line distance from the starting point to the ending point. Taking north as positive and south as negative, the displacement $s$ is the net distance in the north - south direction.
$s = 15\ km-10\ km = 5\ km$

Answer:

Total distance: $25000\ m$, Displacement: $5000\ m$
