    Particle Rotation: Solving for X Coordinate at a Given Time

    Homework Statement A particle rotates counterclockwise in a circle of radius 4.4 m with a constant angular speed of 11 rad/s. At t = 0, the particle has an x coordinate of 2.9 m and y > 0. Determine the x coordinate of the particle at t = 1.22 s. Homework Equations x = Acos(ωt + φ) The...
