7.  Slinky

8.  When weight is suspended from a spring attached to a rod, it will remain in the equilibrium position, unless disturbed.  If the weight is pulled a small distance, it will oscillate indefinitely about the equilibrium position (assuming no friction).  For example, at t = 0, the weight is pulled 3 cm. After 1 sec, it is back to equilibrium. After 2 sec, it is 3 cm above equilibrium… etc.  Find an equation of a sine curve to fit these data.

9.  Simple harmonic motion  All materials have a natural harmonic frequency  This video also includes an example of an oscillating weight on a spring  Videos: http://www.youtube.com/watch?v=eeYRkW8 V7Vg&feature=fvw http://www.youtube.com/watch?v=eeYRkW8 V7Vg&feature=fvw

10.  A satellite is deployed from a space shuttle into an orbit which goes alternately north and south of the equator.  Suppose the satellite is y kilometers north of the equator at x minutes. (y < 0 for south)  It reaches 4500 km, its farthest point north of the equator, 15 mins after launch. Half an orbit later, it is 4500 km south of the equator.  One complete orbit takes 2 hours. 1) Find an equation using cosine to model the distance of the satellite from the equator. 2) How far away from the equator is the satellite 1 hour after launch?
