Answers could be compared. Have students practise finding components of a given vector, graphically and using trigonometry. Whenever possible, these problems could be applied to boats, cars, trains, planes, and local industrial applications such as sawmill green chains and conveyor belts. Assign a sports topic to groups of students. Ask each group to research its sport to identify displacement and velocity vectors involved and to determine how vector addition plays a role in the performance of the sport.
Groups can then present reports to the class.
Possibilities include adding vectors in different orders to verify arrival at the same end point, determining resultants from given displacements, and doing a critical-path analysis to minimize displacement by obstacles such as trees. Invite a navigation course instructor to speak to the class about vector addition. Examples discussed should reflect local values of vector variables such as wind or water velocities. Have students use maps of their region to practise vector addition and subtraction in order to determine combinations of possible displacements to match a given resultant. Students may be restricted to existing roads.
