Oscillations

A spring with a spring constant $k = 200 , N/m$ is stretched by $0.2 , m$ from its equilibrium position. What is the restoring force exerted by the spring?

Which of the following is a characteristic of simple harmonic motion (SHM)?

Two identical springs are connected in series. A block is attached to the end of the combined spring system. If each spring has a spring constant $k$, what is the effective spring constant of the series combination?

Under what condition does the motion of a pendulum approximate simple harmonic motion (SHM)?

In simple harmonic motion, when is the potential energy at its maximum?

A mass-spring system oscillates with SHM. If the total energy of the system is $10 , J$, and at a certain point, the potential energy is $6 , J$, what is the kinetic energy at that point?
