Calculating Resultant Force with two Vectors

hi there

i'm guessing you're troubled with the x-y components of the green line b/c it has an angle of 0.

let's start with the x-components.

cos ( ϴ ) = adj / hyp

cos ( 0° ) = adj / *the magnitude of 70*

rearrange for adj, you get

70 times cos ( 0° ) = 70

When you find the y-component using sine, you get 0.

For the other vector, you'd have to use the angle of 50, then remember the cast rule to determine the signs.

I'm on my phone right now answering lol so if you need a more detailed answer, just respond back and i'll write it out completely for you along with the solution!

talk to you soon
