Question

Vector B (with arrow above) has x, y, and z components of 6.00, 8.00, and 5.00 units, respectively. Calculate the magnitude of B (with arrow above).

______

Calulcate the angle that makes with the x axis.
____°
Calculate the angle that makes with the y axis.
____°
Calculate the angle that makes with the z axis.
____°

Answer 1

√(6^2+8^2+5^2) = √(36+64+25) = √125

Answer 2

i got that part so far

Answer 3

then what?

Answer 4

I would draw a diagram and use trig to find the angles.

Answer 5

like a triangle?

Answer 6

Yeah, using the point you were given and then use trig (inverse tangent) to find the angles

Answer 7

so x would arc tan of (5/8)
y = arc tan of (6/5)
z= arc tan of 6/8

??

Answer 8

For x use x,y
For y use y,z
For z use x,z

Answer 9

so then 6/8,8/5,and 6/5?
