You are flying in a plane that is 125 meters high. You are trying to drop a care package from the plane and hit a target that is 75 meters away. What is the minimum horizontal velocity the plane must have in order for you to hit the target?

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )

The force is push or pull

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
