im scared i might be wrong... but.. so if i rotate it to make the slope my x-axis is the x component w cos (90-theta)? since I am not using the angle given?

assuming you mean the magnitude is 16. vertical is 16 (sin 20) and horizontal is 16 (cos 20)

woh i never did dot products. sorry I am making this hard for you when it is supposedly simple = \ i feel like a retard. but can i get a few things straightened out? so is the VECTOR of this problem is the weight of the rock going downward? you want me to rotate my drawing so that the...

the component is always the original magnitude time cos of the angle … so for one direction it'll be cos(a), and for the other it'll be cos(90°-a) = sin(a) … how did you get those? i didnt read that in my book :(

you want me to rotate the diagram till the vector of the rock... (which is pointing down) is horizontal? so rotate right 90 degrees? am i solving for the length of the slope? sin a = w/length of slope.

i know a vector is made up of an x component, and a y component. but that is when the vector is in a diagonal direction.

Homework Statement A boulder of weight "w" rests on a hillside that rises at a constant angle "a" above the horizontal. The boulder's weight is a force on the boulder that has a direction vertically downward. In terms of "w" and "a", what is the component of the weight of the boulder in the...
