Determine the coefficient of stiffness of the pendulum spring with a period of oscillation of 4 seconds, if a weight of 2 kg is suspended.
T = 4c
m = 2kg
T = 2P * √m / k
4 = 6.28 * √2 / k
4 / 6.28 = √2 / k
0.64 = √2 / k
0.4096 = 2 / q
k = 2 / 0.4096
k = 4.88
Answer: the stiffness coefficient is 4.88
