A vertical spring scale can measure weights up to 225 N . The scale extends by an amount of 12.5 cm from its equilibrium position at 0 N to the 225 N mark. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.65 Hz. Ignoring the mass of the spring, what is the mass m of the fish?

), in radians per second, is determined by the following equation:
(1)
is the frequency, in hertz. 
), in kilograms, is:
(2)
is the spring constant, in newtons per meter.
(3)
- Elastic force, in newtons.
- Spring elongation, in meters.
, 
and 
, then the mass of the fish is:
