If u shoot a gun on a driving car, or with a bow on a riding horse, are the bullets or arrows faster, and why?

Question

I discussed with my family about this situation. I dont get it

Answer 1

Yes. WHen you shoot an arrow or a gun, the bulllet or arrow gets sent forward at a certain speed, say a hundred miles an hour, just to keep it simple. If you are riding or driving forward at, say 20 miles per hour, the bullet will be going 100 mph relative to you, but 120 mph relative to the ground. It also works in reverse: shoot backward and the bullet will still be going 100 mph relative to you but only 80 mph relative to the ground.

You will get to learn all about it when you study vector addition in math class.
