Conical Pendulum Problem: Mass, Length, and Revolutions Per Minute

[mohamed1993]

Homework Statement

A particle of mass 6 kg is attached to the centre B of a light inextensible string
of length 10m. One end of the string is attached to a point A and the other
end to a point C which is distance 8m directly below A. The particle is moving
in a horizontal circle, with both parts of the string taut, at 25 revolutions per
minute.
(i) Find the radius of the circle and the angle  that the string makes with
the vertical.
(ii) Find the angular velocity ! in radians/sec.
(iii) Find the tension T1 in AB and the tension T2 in BC.
