Question

a car goes 5.0 km east, 3.0 km south, 2.0 km west and 1 km north. (a) Determine how far north and how far east it has been displaced. (b) Find the displacement of the vector both graphically and algebraically

Answer 1

Answer:

√13

V1 = 5-2 = 3

V2 = 3-1 = 2

= √V1^2 + V2^2 + 2 × V1 × V2 × cos90°

= √9+4

= √13
