This problem requires a second answer, as demonstrated by this error when I attempt to submit my answer: "Your submission doesn't have the correct number of answers. Answers should be separated with a comma." Please help me find this elusive second answer.
![**Question:**
A player passes a basketball to another player who catches it at the same level from which it was thrown. The initial speed of the ball is 7.2 m/s, and it travels a distance of 4.7 m.
**Problem: Part B**
*What was its time of flight?*
**Instructions:**
Express your answer using two significant figures. If there is more than one answer, separate them by a comma.
**Student Response:**
\[ t = 0.76 \text{ s} \]
**Feedback:**
Your submission doesn't have the correct number of answers. Answers should be separated with a comma.

**Explanation:**
In this problem, we are dealing with the motion of an object in a straight line at constant speed. Given the initial speed and the distance traveled, we can use the formula for constant velocity:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
Given data:
- Initial speed, \( v = 7.2 \text{ m/s} \)
- Distance traveled, \( d = 4.7 \text{ m} \)
Rearranging the formula to solve for time:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{4.7 \text{ m}}{7.2 \text{ m/s}} = 0.652 \text{ s} \]
However, the example student response provided is 0.76 s, indicating possible rounding, a secondary calculation, or another valid approach. The system requires each potential correct time to be listed, and proper rounding to two significant figures.
**Note:** The response field allows multiple answers, separated by commas, in case more calculations yield multiple valid answers.](https://content.bartleby.com/qna-images/question/b9c0e305-fa66-4c78-b971-b9623ece9418/d22b5ad4-6046-4fa0-88d8-21aba3660708/3jepp2d.png)
