Question

True or false??
If a person travels 100m due east and then returns to the same place, his displacement is 200m.

Answer 1

Answer:

False

Explanation:

If a person travels 100m due east and then returns to the same place, his displacement is not 200m then it's 0 displacement

Answer 2

Explanation:

in fid it is shown that the person start from the point A to point B towards east then person take turns 60degree turns toward north and again move from point B to point C .

the distance between point A to B and point B to point C is same which is 100 m.

angle ABC would be equal to 120 degree .

and other angle in triangle would be same because of property ANGLE OPPOSITE TO EQUAL SIDES ARE EQUAL.let unknown angle be a.

the remaining angle will be

120+2a=180(sum of all angle in triangle is 180)

a=40;

{sin40=0.6428; sin120=0.866 ; cos30=0.866}

I hope it helps you ✌️✌️
