Homework Statement
A solid sphere of radius 1 m and mass 5 kgis placed in a wedge with θ = 29 ◦
The inner surfaces of the wedge
are frictionless.
The acceleration of gravity is 9.8 m/s2 .
Determine the force exerted by the wedge
on the sphere at point B. Answer in units
Figure, ASCII style!

The Attempt at a Solution
Alright, so I tried this.
Fx=a+bcos(119)
Fy=bsin(119)-5*9.8.
This shouldn't be as annoying as it is. I mean, by my method, B is easily given, but the answer i get is wrong. Which means I'm not seeing something. Ideas?
