Question

    Use the polygon method to determine the resultant of the following displacement.

(Scale: 1 km = 1 cm) D₁ = 2.0 km to the east, D₂ = 5 km, 35 N of E, and D₃ = 7.0 km, 60 N of W.

Answer 1

1. Draw D1: 2cm east
2. Draw D2: 5, 35 degree North of east
3. Draw D3: 7 cm , 60 North of W

Ans : measure the resultant magnitude and direction

Resultant = 4.2 cm 45 of North west

Scale 1 cm = 1 Km and

Ans is 4.2 Km
