a car changes its position from 52km west to 139 km east. what is the cars displacement?

Displacement is the straight-line distance from the initial position to the final position, considering direction.

In this case:
- The car starts at 52 km west (which we can treat as -52 km).
- It ends at 139 km east (which we treat as +139 km).

The displacement is calculated as:

\[
\text{Displacement} = \text{Final Position} - \text{Initial Position} = 139\, \text{km} - (-52\, \text{km}) 
\]

\[
\text{Displacement} = 139\, \text{km} + 52\, \text{km} = 191\, \text{km}
\]

So, the car's displacement is **191 km** to the east.

Would you like to delve into the concept of displacement or have any questions? Here are some related questions to consider:

1. How is displacement different from distance traveled?
2. What would be the displacement if the car moved from 139 km east to 52 km west?
3. How would you calculate displacement if the car moved in a non-straight path?
4. What is the significance of the sign (positive or negative) in displacement?
5. How would displacement change if the initial and final positions were the same?

**Tip:** Displacement is a vector quantity, meaning it has both magnitude and direction, unlike distance, which is scalar and only has magnitude.

A car changes its position from 52 km west to 139 km east. What is the car's displacement?

Learn how to calculate a car's displacement as it moves from 52 km west to 139 km east. This problem covers the concept of vector displacement, using the formula: Displacement = Final Position - Initial Position. Ideal for students in Grades 6-8.
