A particle of mass 2.5 kilograms is attached to one end of a light, inextensible string of length 75 cm. The other end of this string is attached to a point A. The particle is also attached to one end of an elastic string of natural length 30 cm and modulus of elasticity 2. N. The other end of this string is attached to a point B, which is 60 cm vertically below A. The particle is set in motion so that it describes a horizontal circle with centre B. The angular speed of the particle is 8 rads-1 Find 2, giving your answer in terms of g.
