If there was a ball falling from a tree and there was a guy under the tree, the balls was falling 12 mph and the guy under the tree has 2 seconds to escape. Did the ball land in his head or did he dodge it?

It was going 12 miles per hour and he noticed it, but he had 2 seconds left to dodge it, if the ball is falling 12 mph then the tree is pretty big and he had enough time to escape, so yes he did dodge it.

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
