Do you know what is the difference between the "magnitude of the displacement vector" and "the actual distance skated" (parts a and b)?

anonymous · Answer

Magnitude of displacement is the straight line distance from the beginning of a path to the end of the path. What is the length of the straight line drawn from the beginning position to a point half way around the circle?
