Question

1)A harmonic oscillator consisting of a spring with spring constant 9.8 N/m and an unknown mass has a frequency of 0.9 Hz. What is the mass?

2)

An ideal massless spring is hanging vertically. When a 0.93-kg mass is attached to the spring, the spring stretches by 5 cm before reaching a new equilibrium. Then the mass is displaced by 1 cm from the new equlibrium. What is the frequency of the resulting oscillation?

Explanation / Answer

frequency = sqrt(spring constant / mass) / (2 * pi)

0.9 = sqrt(9.8 / mass) / (2 * pi)

mass = 0.3064 kg
