Question

A balut vendor walking 800 m, north and then 100m,west will have a resultant vector of​

Answer 1

Explanation:

person moves 30m North then 20m east than 302 meter southwest.

The movement along north direction, Vector OY=30j^

The movement along east direction, Vector YX=20i^

Movement along south west direction,XZ=

302(cosθi^+sinθj^)

Vector XZ=302(cos45A0i^+sin45A0j^)=30i+30j

Using triangle vector law,

OX=20i+30j

XZ=30i+30j

In triangle XZO,OZ is resultant from origin.

OZ=OX−XZ

OZ=20i+30j−30i−30j

OZ=−10i

Hence, The position of person from origin is 10m West.

Answer 2

Answer:

Explanation:

Hey mate,

Here is ur answer

From the starting point up to the northwest direction, it forms a quadrilateral polygon whose sides are 50m, 30m, 30m and 58.74m as the last side joining the last point and starting point. The last side of the polygon is the total distance from the last point to the starting point which is calculated as 58.74m. The interior angles of the polygon from starting point to end are 60.65 degrees, 90 degrees, 135 degrees, and 74.35 degrees having a sum of 360 degrees..
