Question

What is the opposite of ‘4m in the east direction’?  ​

Answer 1

Answer:

in the opposite direction of east). hence, distance 4+(-3)m=1m. and displacement = 1-(-3)m=(1+3)m=4m

Answer 2

Answer:

distance covered is equal to the sum of three distances which is equal to = 3+4+12=19m

If initial position is considered to be at origin then the final position of the man is 3

$3i + 4j + 12k$

So, the displacement covered by him =

$\sqrt{ {3}^{2} + {4}^{2} + {12}^{2} } \\ = 19m \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
