measured in cycles per second. As the frequency is increased, the eye initially perceives a series of flashes of light, then a coarse flicker, a fine flicker, and ultimately a steady light. The frequency at which the flickering disappears is called the fusion frequency. The table below shows the results of an experiment in which the fusion frequency F was measured as a function of the light intensity 1.

93.5 Jimmy has a spring. The spring constant jimmy knows to be 6N/m. Jimmy's spring is horizontal & one end of jimmy's spring is stuck to the wall and the other is stuck to an object of mass. Jimmy would like his spring to weigh items. Jimmy puts the spring into motion and finds that 0.3Hz is the frequency in cycles per second. Help jimmy find the mass of the object stuck to the spring. Assume that there is no friction force present. Your final answer must be a whole number and must have appropriate units.
