## Homework Statement

A solid uniform 50kg ball of diameter 30cm is supported against a vertical frictionless wall using a thin 35cm wire of negligible mass (the wire is attached to the wall, the ball is attached to the wire and rests against the wall). Make a free body diagram for the ball and use it to find the tension in the wire. How hard does the ball push against the wall?

## Homework Equations

∑Fx = max

∑Fy = may

(no given equations - these are ones i would fine useful)

## The Attempt at a Solution

i have no idea how to set up this problem. i know free body diagrams, but i don't know how to orient my coordinate system for this problem. Please don't help me solve the problem, but pleasepleaseplease help me with how to set it up.
