Emily passes a soccer ball 6.0 m directly across the field to Kara. Kara then kicks the ball 14.5 m directly down the field to Luisa. What is the ball’s total displacement as it travels between Emily and Luisa?

To determine the ball's total displacement as it travels between Emily and Luisa, we need to consider the movements in terms of vectors and use the Pythagorean theorem.

1. Emily passes the ball 6.0 meters directly across the field to Kara (horizontal movement).
2. Kara then kicks the ball 14.5 meters directly down the field to Luisa (vertical movement).

These movements form a right triangle with the following legs:
- Horizontal leg = 6.0 meters
- Vertical leg = 14.5 meters

The total displacement is the hypotenuse of this right triangle. We use the Pythagorean theorem to find it:

\[
\text{Displacement} = \sqrt{(6.0 \, \text{m})^2 + (14.5 \, \text{m})^2}
\]

First, we calculate the squares of the legs:

\[
(6.0 \, \text{m})^2 = 36.0 \, \text{m}^2
\]

\[
(14.5 \, \text{m})^2 = 210.25 \, \text{m}^2
\]

Now, we add these values:

\[
36.0 \, \text{m}^2 + 210.25 \, \text{m}^2 = 246.25 \, \text{m}^2
\]

Finally, we take the square root of the sum to find the displacement:

\[
\text{Displacement} = \sqrt{246.25 \, \text{m}^2} \approx 15.7 \, \text{m}
\]

So, the ball’s total displacement as it travels between Emily and Luisa is approximately 15.7 meters.
