A postal employee drives a delivery truck along the route shown in the figure: However, please replace 2.6 km by 4.8 km and 4.0 km by 3.9 km. You determine (A) the magnitude (in km) of the resultant displacement AND (B) the direction (in degree between 0 and 90; north of east) of the resultant displacement. The question is ... What is (A) plus (B)? cf. pi = 3.14159265 Q01 - Q10) No need to put down the unit/dimension for the answer.

Step 1
This can be done by using the Pythagorean theorem, as we are dealing with a right triangle. The theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the sides Show more…

A postal employee drives a delivery truck over the route shown in Fig. E1.25. Use the method of components to determine the magnitude and direction of her resultant displacement. In a vector-addition diagram (roughly to scale), show that the resultant displacement found from your diagram is in qualitative agreement with the result you obtained by using the method of components.
