Question

Draw the following vectors using the scale 1 cm = 50 km/h. Plant the tail at the origin. A. 200 km/h on a bearing of 020° B. 75 km/h S 10° W C. 350 km/h NE

Answer 1

a)

200 km/h on a bearing of 020°

Scale 1 cm = 50 km/h.

`Length\text{ = }(200)/(50)\text{ = 4cm}`

b)

B. 75 km/h S 10° W

`Lenght\text{ = }(75)/(50)\text{ = 1.5cm}`

C. 350 km/h NE

`Length\text{ = }(350)/(50)\text{ = 7cm}`
