Question

A boy travel 3m east,then 5 m towards north,then 3m again east and 3m towards north. find distance travelled and his displacement

Answer 1

Answer:distance =3+5+3+3 =14m

Displacement is = 11.66m

Explanation:this may help you

All the best

Answer 2

Answer:

Distance = 14m and Displacement = 10m

Explanation:

Since distance is a scalar quantity, we only need to consider the .directions. Hence, distance here would be 3+5+3+3 = 14m

Now, displacement is a vector quantity. Hence, we have to consider the directions. Here, the boy has travelled a total of 3+3 = 6m to the east and

5+3 = 8m to the north. Displacement will be in the direction of the straight line joining initial and final points, hence here it will be the hypotenuse formed by these two distances ( 6m and 8m ). The magnitude of displacement will be, as per Pythagoras theorem, equal to $\sqrt{}$$6^{2}$+$8^{2}$ = 10m

Hope it helps!
