1. What is the time period of a spring (k=42 N/m)
with a 80 kg mass attached?
2. A 2 kg mass is suspended from a spring, causing
a 30 N elastic force as it stretches by 0.72 m.
a) What is the value
of k for that spring?
b) How long is one
period?
3. A 44 kg rock is suspended from a spring which
stretches from its relaxed length of 0.60 m to a length of 0.85 m.
What is the k value for that particular spring?
4. What is the time period of a pendulum that is
1.8 m in length?
5. Using all 3 equations, prove that x=L if the
elastic force is equal to the weight of a suspended mass.
