Ball attached to string attached to wall, find force against wall

[QUOTE="jackarms, post: 4680468, member: 500976"] Hello! So I think the setup for this will look like the ball right up against the wall, with the wire going up to where it's anchored on the wall at the pivot. You can find the angle with right triangles. So for forces you'll have the tension going up along this angle, the weight force going straight down, and the normal force from the wall onto the ball that's horizontal. For coordinate systems it really doesn't matter. The natural system would be to have the y-axis up and down along the wall, and the x-axis perpendicular to that. I'll give you a hint though -- if you have the y-axis going along the wire, and the x-axis corresponding to that, you can solve it more efficiently. [/QUOTE]
