Consider a spring with a spring constant of 10.0 N/m supporting a 2.28 kg mass on a horizontal table top. The mass is pulled so the spring is initially stretched 10 cm. Friction causes the oscillation to half every 4 seconds. Sketch a graph of the position of the mass with respect to time. Write the equation for this motion.

The frequency w of the oscillator is 0.978 times the frequency w0 of the undamped oscillator. If the initial amplitude of oscillations is equal to A, what is the amplitude after 4 complete oscillations?

A mass is hanging at rest on a spring. You pull it down 7.00 cm and release it. What is the amplitude of the resulting oscillation? In Problem 15, what is the difference in height between the highest and lowest point of the oscillation?

A simple pendulum of mass 2.3 kg and length 0.28 m on planet X, where the value of g is unknown, oscillates with a period of 1.3 s. What is the g on planet X, in m/s2? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
