A small trolley of mass 2.0 kg resting on a horizontal turntable is connected by a light spring to the centre of the table. When the turntable is set into rotation at a speed of 300 rev/min the length of the stretched spring is 40 cm. If the original length of the spring is 35 cm, determine the force constant of the spring.
