You are expected to demonstrate vector techniques from Topic 1. Using alternative methods will result in low or no marks. 1. An object is being pulled by two forces F1 and F2. The force F1 is pulling in the direction 60o north of west with a force of 20 Newtons, while the force F2 is pulling in the direction 30o north of east with a force of 10 Newtons. (b) Express F1 and F2 as 2-dimensional vectors. (c) Find a third vector representing a third force F3 which can be applied to ensure the object does not move. (d) Give the direction (as an angle in degrees north/south of east) that F3 is pulling and the force (in Newtons) showing all working.

Extend and Apply Note: You are expected to demonstrate vector techniques from Topic 1. Using alternative methods will result in low or no marks. 1. An object is being pulled by two forces Fi and F2. The force Fi is pulling in the direction 60" north of west with a force of 20 Newtons, while the force F2 is pulling in the direction 30 north of east with a force of 10 Newtons. (b) Express F1 and F2 as 2-dimensional vectors. (c) Find a third vector representing a third force F3 which can be applied to ensure the object does not move. (d) Give the direction (as an angle in degrees north/south of east) that F3 is pulling and the force (in Newtons) showing all working.|
