The diagrams show six different arrangements of a box attached to a massless spring on a frictionless surface. The spring constant and mass of the box are shown in the diagrams. The rightmost vertical dashed line shows the position of the right edge of the box when the spring is neither compressed, nor stretched. The boxes are then pushed to compress the spring by the amount shown, and then let go. At that time, the boxes start oscillating back and forth.  Rank the periods  of oscillation for each box.

A block with mass  = 10,000 kg is attached to a massless spring with a spring constant  = 25 N/m. At time  = 0 s, the block is observed to be 100 cm to the left of the equilibrium position and moving toward the left with a speed of 12 cm/s. What is the position of the object at   = 175 s?

A turntable (thin disk) has a mass of 2.0 kg and radius of 0.15 m.  It is initially spinning with angular frequency of 15 rad/s.  A 0.50 kg mass is dropped onto its rim and sticks.  Find the angular frequency (in rad/s units) after the mass is stuck on the rim.
