Friction is a force that holds back the movement of a sliding object. You will find friction everywhere that objects come into contact with each other. The force acts in the opposite direction to the way an object wants to slide.
Answer:
Explanation:
The package had the same velocity as the plane when it was dropped. Newton's 1st Law says that "an object in motion tends to stay in motion, at the same velocity, in a straight line unless acted on by an outside force".
There only outside force acting on the package was its weight -- that force is straight down. The horizontal velocity that the plane gave the package continued (as Newton said it would), so as it fell, horizontally it kept pace with the plane.
The answer is A.68 degrees
