A velocity vector has a magnitude of 720 m/s. Two students draw arrows representing this vector. Clarisse chooses a scale such that 1 cm → 100 m/s. a. What is the length of the arrow that Clarisse draws? b. Francois's arrow is half as long as Clarisse's. What is Francois's scale? c. Is one student's choice better than the other? If so, what makes it a better scale?
