Answer 1

Given :

A person moves 8.0 m towards north, takes a right turn and moves 6.0 m

Required to find :

Distance travelled

magnitude of Displacement

S O L U T I O N :

Distance travelled = Total distance covered by man

= 8.0m + 6.0 m

= 14m

So, Distance travelled is 14 m ‎ㅤㅤㅤㅤㅤㅤㅤㅤ____________________

As we know that,

Displacement is the shortest Distance between initial point and final point. So, Displacement is here BC i.e the shortcut. We can find it's Displacement by applying Pythagoras theorem.

For better understanding refer attachment.

AB² + AC² = BC²

BC = √AB² + AC²

AB = 6m , AC= 8m

Displacement (BC) = √(8)² +(6)²

BC = √64+36

BC = √100

BC = 10 m

So, the Displacement is 10m .[tex][/tex]
