Help on this question. I can't seem to get
it right
Consider two force vectors in the xy-horizontal plane. Suppose a force of 18.7 N pointing along the +x-axis is added to a second force of 20.1 N directed at 55 degrees to the +x-axis , also in the horizontal plane. Find the resultant vector for this sum.
i can't get this right
I've calculated the angle of z to be 24 but can't figure out why
this is wrong then
Sketch the phasor diagram for an ac circuit with a 10512 resistor in series with a 92.5-mH inductor and a 32.2 uF capacitor. The frequency of the generator is 60.0 Hz. Draw the vectors with their tails at the dot. The orientation of your vectors will be graded. The exact length of your vectors will not be...
the furthest i could get is that the dot product between vector
N and vector V, as well as vector X and vector V must be zero but
that's about it. I get stuck when trying to use the cosine relation
with the dot product but since the question doesn't allow me to
write it in terms of an angle, i can't really use that. If someone
could show me how this would help incredibly!

Name: Vectors Review Score: /22 Many of the quantities you will encounter in this course are vectors. You will need to be proficient at basic vector manipulations: addition, subtraction, dot products and cross products. This worksheet is a refresher. Chapter 3 of your textbook explains vectors at the level we will be using them in the course. Please review it Below is a list of six...
