Question

PLEASE HELP WITH THIS VECTORS QUESTION!



Determine the resultant:

25 N at 10° to the horizontal and 30 N horizontally.

Please show all work, Thanks (:

Answer 1

HEY CALLISTO REMEMBER ME? :D

Answer 2

Yes :)

My method is a little stupid... sorry
Consider the horizontal component
Horizontal component of the resultant vector
= 25cos10 + 30
= 54.62

Vertical component of the resultant vector
= 25sin10
= 4.34

Resultant vector
\(= \sqrt{54.62^2 + 4.34^2}\)
= 54.79

Angle: \(tan^{-1} 4.34/54.62 = 4.53 °\) to the horizontal

Answer 3

THANKS :)
How should I write my therefore statement?

Answer 4

Any ideas?

Answer 5

Eh?!
Therefore, the resultant vector is 54.79N at 4.53° to the horizontal?!
Hold on... seems I made mistakes there... lemme check it first :|
