Use vectors to model and solve application problems.
Remarks
Example: The vector
represents the displacement of a wagon that is pulled with the force 
.The work done in moving the wagon in the direction of is defined to be the component of in the direction of times the distance the wagon moves. Show that this definition can be written as , 
where α= the angle between and . And find the work done if = (10,3) and = (25,0).
