Question

a body travel distance of 3km west and 4 km north and finally 9 km towards west. Find distance travelled and displacement? ​

Answer 1

Answer:

ax/bx = oa/ab = 1/3

thus ax = 1 km

and bx = 3 km now using Pythagorous theorem in both triangles we get

ox = 3.16 km

CX = 9.49 km

thus, total displacement = oc = 12.65 km
