Calculating Bank Angle for Airplane Flying at 50ms^-1 with 300m Radius Turn

[Kenny Lee]

A small airplane makes a turn of 300m radius, while flying at 50ms^-1. Determine the angle at which it banks with the horizontal plane.

Anyone any idea on how to do this?
Please I really need help.

Just balance the forces: gravity, centrifugal and wing lift

yea? okay i'll give it a try. Thanks
doesn't work... Have no lift values...or mass even, so no weight and centripetal. Nm thanks anyway.
