Unit 3: Motion in Two-Dimensions

Problem Set A

 

Problem 6:

What is the magnitude of the resultant displacement (in meters) of a walk of 46.1 m followed by a walk of 64.8 m when both displacements are in the eastward direction?

 

 TIP:

The addition of two vectors which are directed in the same direction is a simple task. A quick diagram of the two vectors should help you get started. If you are still having difficulties, then you ought to view the clever online animation at the Multimedia Physics Studios. If you do, observe how the angle between the two vectors effects the magnitude of the restultant.
