(a) What happens to the magnitude and direction of a vector when you negate the vector? (b) When is the average speed equal to the magnitude of the average velocity, and when are they different? (c) Velocities are given two subscripts when discussing relative velocity. What happens when you reverse these two subscripts? Give an example.
