Diagnostic Misconceptions - Perpendicular Vectors

Test yourself on Diagnostic Misconceptions - Perpendicular Vectors

• Two forces of 10 N act on an object, as shown.
  What is the size of the resultant force on the object?

• An object has velocity vectors of 5 m/s and 10 m/s in the horizontal and vertical direction as shown.
  What is the magnitude of the resultant velocity?

• An aeroplane has an airspeed of 100 m/s due North and is being blown sideways by a crosswind of 40 m/s coming from due West.

  What is the size of its resultant velocity?
