Calculate the resultant force. Include directional arrows to support your answer. c) A force 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 3N 2N 7N Calculate the resultant force acting on the box. Include diagrams to support your answer.
