	/// Example05: Circular Motion with Constant Angular Speed
	/// A particle rotates counterclockwise in a radius 3.00 m 
	/// with a constant angular speed of 8.00 rad/s. At t=0, 
	/// the particle has an x coordinate of 2.00 m and is moving 
	/// to the right.
	/// (A) Determine the x coordinate as a function of time.
	/// x = 3 \cos(8t-0.841)
	/// (B) Find the x components of the particle velocity 
	/// and acceleration at any time t.
	/// v = -24 \sin(8t-0.841)
	/// a = -192 \cos(8t-0.841)
