What is the Force Exerted by a Ball Against a Wall Supported by a Thin Wire?

[poorfish10]

Hi,
I am having trouble figuring out how to start this problem, I have a free body diagram, but I am not sure which equation to use to help me solve for this, please help!

A solid form 42 kg ball of diameter 32 cm is supported against a vertical frictionless wall using a thin 30cm wire of negligible mass, how hard does the ball push against the wall?

Thank you!

The ball is not accelerating so you can use Newton's first law (sum of the forces = 0).

yes, but the center of the ball (where the mass is to be assumed) is 16cm away from the wall. so you have a triangle that is a=16 b=43.1 c=46, don't you ave to take that into account?
