# Vector algebra: Conceptual problems

1. Given the vector 25 knots [southeast], describe the opposite vector and label and draw a scale drawing of the vector and its opposite. (5 marks)

2. You are given the following vectors.

a = 5 N [south]

b = 4 N [north]

c = 2 N [west]

d = 4 N [east]

Draw scale diagrams to find:

a. a + 3a (2 marks)

< >

b. c - d (2 marks)

< >

c. b +2c + 2 (2 marks)
