Calculate force required to eject a sheet metal part from a die cavity

[Mike_5158]

How do I calculate the force required to eject a sheet metal part from a die cavity.
Coefficient of friction: 0.35
Surface area: 521.26 mm2
Elastic modulus: 68.9 GPa
Material: 3003 Aluminium
Material Thickness: 0.7mm
Any help would be much appreciated.
Thanks

Welcome, @Mike_5158 !

More things are involved in that calculation.
Could you provide a drawing or diagram of the part?
