Question
To develop a computational model of the satellite's velocity based on the distance from the Earth and the time elapsed, I would create a function that takes two lists as inputs—one for distances (X) and one for time (Y). The function would then compute the velocity (V) using the formula
, iterating through each pair of values in the lists. Finally, I would test the implementation using the Trinket tool to ensure the calculations are correct and the output is as expected.

To create a computational model of a satellite's velocity based on the distance from Earth and the time elapsed, you can follow these steps to implement the function. Here's a Python function that takes two lists: one for distances and one for time, computes the velocity for each corresponding distance-time pair, and returns a list of velocities.
The formula for velocity given distance (d) and time (t) is:
\[ V = \frac{d}{t} \]
If the time is zero, you should handle that case to avoid division by zero.
Here’s how you can implement this:
```python
def calculate_velocity(distances, times):
# Initialize an empty list to store the velocities
velocities = []
# Iterate over the pairs of distances and times
for d, t in zip(distances, times):
if t == 0: # Check for division by zero
velocities.append(float('inf')) # You could also use None or any other placeholder
else:
v = d / t # Calculate velocity
velocities.append(v) # Append the calculated velocity to the list
return velocities
# Example Usage:
distances = [10000, 20000, 30000, 40000] # Example distances in meters
times = [10, 20, 30, 0] # Example times in seconds (last time is zero for testing)
velocities = calculate_velocity(distances, times)
print(velocities) # This will print the calculated velocities
```
### Explanation:
1. **Function Definition**: The function `calculate_velocity` takes two lists `distances` (X) and `times` (Y).
2. **List Initialization**: An empty list `velocities` is created to store calculated velocities.
3. **Iterating with `zip`**: Using `zip`, the function loops through each distance and corresponding time.
4. **Division by Zero Handling**: If the time is zero, it appends `float('inf')` to signify infinite velocity (you can choose a different way to handle this if preferred).
5. **Velocity Calculation**: If the time is not zero, it calculates the velocity and appends it to the list.
6. **Output**: Finally, the function returns the list of velocities.
### Testing the Implementation:
You can test this implementation in the Trinket tool (or any Python environment) by providing sample distance and time values, as shown in the example usage. The output will be a list of computed velocities based on the input data. If the input times contain a zero, you will see how the function handles that case as well.
