Question

3. If a vector that is 1 cm long represents a

velocity of 10 km/h, what velocity does a vec-
tor 2 cm long drawn to the same scale repre-
sent?

Answer 1

A velocity of
`20 \: km/h`

Step-by-step explanation:

Since the magnitude of the vector is equal to the magnitude of velocity, velocity of the 2 cm vector represents a velocity of $10\times 2= 20 \: km/h$.
