Question

a man travels a distance 1.5 meters towards east and then 2 meter towards south and then 4.5 towards east.
a) what is the total distance?
b) find the resultent displacement.​

Answer 1

Explanation:

a) Total distance = ( 1.5m + 2.0m + 4.5m )

= 8m

b) Displacement =

${oc}^{2} = {dc}^{2} + {do}^{2}$

$oc = \sqrt{ {dc}^{2} + {do}^{2} }$

$oc = \sqrt{ {6}^{2} + {2}^{2} }$

$oc = \sqrt{36 + 4}$

$oc = \sqrt{4(1 + 9)}$

$oc = \sqrt{ {2}^{2}(1 + 9) }$

$oc = {2}^{2} \sqrt{10}$
