The oscillation

The oscillation of a mechanical oscillator can be used to measure weight. A body of unknown weight is suspended on a spring with a stiffness of 20 N times m. The resulting oscillator oscillates with a frequency of 1.6 Hz. Find the weight of the body.

Correct answer:

m =  0.1979 kg

Step-by-step explanation:

f=1.6 Hz k=20 Nm g=9.81 m/s2  f=12π km  2π f=km  4 π2 f2=k/m  m=k4π2 f2=204 3.14162 1.62=0.1979 kg
