Given the two position vectors r1 = (-2.,0, 8.0, -2.0) and r2 = (4.0, -2.0, 2.0), in meters, find (a) their resultant and (b) the angle the resultant makes with the x-axis.
Homework Answers
r1=(-2,8,-2) and
r2=(4,-2,2)
(a)Now we have to find out the resultant of the two vectors, so we just have to add the two vectors.
Resultant will be=
[(-2+4),(8-2),(-2+2)]
=(2,6,0)
And the magnitude will be,
=6.32
(b)
The angle it makes with x axis is,
=71.5650

In this lab you will be given two different sets of vectors to add together. In Activity 1, you will add position vectors: in Activity 2 you will add forces. Vector addition is an important concept in physics. To be well prepared for the lab you need to solve the following example. Make sure to show all your work in detail. Write the equations first, and then plug in the numerical values. Do not forget to do unit conversions. Use...
