A particle executes simple harmonic motion with an amplitude of 9.00 cm. At what positions does its speed equal one-half of its maximum speed? larger number       cm smaller number        cm

The function x = (6 m) cos[(4π rad/s)t + π/8 rad] gives the simple harmonic motion of a body. At t =3 s, what are the (a) acceleration, and (b) phase of the motion?

Two particles oscillate in simple harmonic motion along a common straight-line segment of length 0.86 m. Each particle has a period of 3.8 s, but they differ in phase by π/6 rad. (a) How far apart are they 1.4 s after the lagging particle leaves one end of the path? (b) Are they then moving in the same direction, toward each other, or away from each other?
