Determine the mass of a load performing harmonic oscillations on a spring with a stiffness of 40 if the period of its oscillation coincides with the period of oscillation of a mathematical pendulum 5 meters long.
Thus, we get
T = 2 * pi * sqrt (L / g)
T = 2 * pi * sqrt (m / k)
L / g = m / k
m = L * k / g = 5 * 40/10 = 20 kg
In response, write down the number 20 kg.
