Question

A body move 3m north , then 4m east and 6m south . Calculate the ratio of distance to displacement travelled by body​

Answer 1

According to the question -

➜ A body move 3m North ,

➜ Then 4m east

➜ And then 6m South

➜ Calculate the ratio of distance to displacement travelled by body .

Distance travelled by body

➜ 3m + 4m + 6m

➜ = 13m

Displacement travelled by body

$\small \bold{ \sqrt{ {3}^{2} + {4}^{2} + {6}^{2} }}$

$\small \bold{ \sqrt{9 + 16 + 36}}$

$\small \bold{ \sqrt{61 = 7.81}}$

Ratio = distance : displacement

➜ 13:7.81

$\small \bold{ \frac{13}{1} \frac{.}{.} \frac{781}{100}}$

➜ 13 : √61
