if I shovel snow after storm exerting a force of 30.0N at an 60.0 angle to teh vertcial... what will be my horziontal and vertical componets

of the force exerted by marcie?

You can use trig functions. cos(60) = x/30N and sin(60) = y/30N
Solve for your x and y and those are your component vectors.

To see it more clearly, have a sketch.

Draw your 30 N force.

x and y are the horizontal and vertical components respectively. Use your trigonometric ratios to find them!

Image needs to be rotated 90 degrees, doesn't change anything but direction though.

I like to have at least one value positive, so, positive x I go!
