Question 2
a.

State the two properties needed to completely specify a vector quantity.

[2]
b.

A ship is sailing due East at 12.0 m/s in calm water. A strong ocean current starts to flow due South at 5.0 m/s.

Draw a vector diagram to find the resultant velocity of the ship. Use a scale of 1.0 cm=1.0 m/s1.0\text{ cm} = 1.0\text{ m/s}1.0 cm=1.0 m/s.

From your diagram or by calculation, find:

  • the resultant speed of the ship
  • the angle between the resultant velocity and the easterly direction.
