Okay. So next bit. Consider the following:
You are a YouTuber content creator. You create content on the latest new car. So, you want to film your mate driving this new model. You put on your GoPro camera to film him driving along a motorway. He is travelling at 50 mph. You are filming alongside of him in your car.
Question: how fast do you need to travel to keep up with him, so that he appears perfectly static in your video, with the background visibly whizzing by: is it:
- Faster
- 50 mph
- Slower
- Stationary
- Haven't a clue?
