Forces in Two Dimensions – Practice


1) A force of 540N acts on an object at an angle of 48° above the horizontal. Calculate the horizontal and vertical components of this force:

2) A force of 0.5N south and a force of 1.2N east act on an object. Calculate the resultant force acting on the object:

3) Two forces act on an object. The first force acts north and the second force acts east. The resultant force is 1200N N15°E. Calculate the magnitude of the two forces:


Quick Answers:

1) Horizontal = 361N, Vertical = 401N

2) 1.3N S67.4°E (112.6°T)

3) FE = 311N, FN = 1159N
