A body oscillates with simple harmonic motion according to the equation:

x = (6.0 m) cos [ ( 3 pi rad/s )t + pi/3 rad ]

At t = 2.0 s, what are (a) the displacement, (b) the velocity, (c) the acceleration, and (d) the phase of the motion?

Also, what are (e) the frequency and (f) the period of the motion?

Explain your work. Thanks! :)

I see a lot of it on the east coast. I think it feeds on either fabric or wood because I always see them on this material.

They look like a worm because it's long but it really has legs and 2 pointy things at its tail. They can run really fast for something its size. I don't know how many legs it has. I think they are fairly common in the area.

I have been finding them on my bed lately before I go to sleep and it has been freaking me out. Are they poisonous? Will they feed on me?
