y meter 2 3 4 5 6 sec A THW (with amplitude of 1 m) is traveling to the right (+ dir) with velocity 2 m/s. The following graph describes how the particle at x = 3 m vibrates. 1) Draw a snap shot of the wave at t = 1 second. 2) Find an expression that describes the THW. 3) Describe your procedure for drawing your graph AND for finding all variables in your THW expression.

A. On the linearized graph of period vs. chord length, what are the units of the slope? B. On the linearized graph of chord length vs. period, what are the units of the slope?

A pendulum swings back and forth from a string. When it is lying motionless it is y=6 ft from a nearby wall. When the pendulum is furthest from the wall, it is 9 ft. It takes 20 seconds to complete one cycle. Suppose you start timing the pendulum when it is furthest from the wall.a) Sketch a graph of this situation. b) Write an equation of this sinusoidal.

5. Simple Harmonic Motion: An object is attached to a coiled spring. It is pulled down a distance of 6 inches from its equilibrium position and released. The period of the motion is 4 seconds. a. Show your work for modeling an equation of the objects simple harmonic motion d = acos wt where d is distance from the rest position and the period is , w > 0. A hand sketch may be helpful, but is not required. b. What is the frequency? c. When t = 3 find the distance and interpret it.
