Recall: a scalar is a quantity measured by only a number. For any vector, u , multiplied by a scalar k, the resulting vector k - u ; i) ii) iii) iv) Eg.1: A car is traveling at 100 km/h East. The cars velocity is represented by v . ) ) > Draw vectors 0.5 v , 2 v , v and given an interpretation for each. Scale: 1 cm is equivalent to 10 km/h.
