SUMMARY
The discussion centers on calculating the new length of a spring with a spring constant of 12000 N/m when a 65 kg weight is applied. The force exerted by the weight is calculated as 637.65 N using the equation f = m * g, where g is the acceleration due to gravity (9.81 m/s²). The displacement of the spring, calculated as x = 637.65 N / 12000 N/m, results in a change of approximately 0.053 m or 5.3 cm. This displacement is reasonable when considering the spring's original length of 30 cm.
