a) Define the term 'resultant force'. b) Two forces 5N and 3N act to the west. Calculate the resultant force. Include directional arrows to support your answer. c) Aforce of 20 N acts to the east, and a force of 10N acts to the west. Calculate the resultant force. Include directional arrows to support your answer. d) A box is subjected to the following parallel forces: 5N IN 3N 7N Calculate the resultant force acting on the box. Include diagrams to support your answer. e) An object is travelling at 15 ms at an angle of 38 to the horizontal. Using the diagram below as a guide, find the horizontal and the vertical components of the object's velocity. 15 ms' ) ] f) Calculate the horizontal and vertical components of a vector 195 ms acting at an angle of 40 to the horizontal Plane
