- Enter the velocity in meters per second (m/s).
- Enter the time in seconds (s).
- Click the “Calculate” button.
Formula & Methodology
The calculator uses the formula for distance: Distance = Velocity × Time. Katherine Johnson would have used this formula in her calculations.
Real-World Examples
Example 1: Freedom 7
For Alan Shepard’s Freedom 7 mission, Johnson calculated the distance traveled using a velocity of 8,000 m/s and a time of 150 seconds. The result was 1,200,000 meters.
Data & Statistics
| Mission | Velocity (m/s) | Time (s) | Distance (m) |
|---|---|---|---|
| Freedom 7 | 8,000 | 150 | 1,200,000 |
| Mercury-Redstone 4 | 7,500 | 120 | 900,000 |
