    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)
