A mass hanging on a spring with spring constant 20 N/m has a period of 4 π s. (Note that π = 3.1415). What is the value of the mass (in kg)?
3) A mass spring oscillator is created. It has a period of 6 seconds and an amplitude of 2 cm. When a 0.70 kg-object is attached to the spring hung vertically, it stretches 0.15 m from the equilibrium position. (The following questions can be answered in either order depending on method ) A. What is the maximum speed of the oscillator? B. What is mass hanging on the spring?

1) What should the period of a spring oscillator be if it has a mass of 5 kg and a spring constant of 25 N/m? What would the new period be if the mass is doubled?
A pulsar is observed to have a period of 1.6 seconds. Move the left point of the line to show where on the graph the pulsar's period is now (at time 0), and move the right point of the line to show how the period will change over time. 2.8 2.6 2.4 2.2 1.8 1.6 1.4 1.2 0.8 0.6 0.4 0.2 0 1 2 3 45 6 7 8910 Time (millions of years)
