A point rotates about the origin in the xy plane at a constant radius of 0.216 m and angular velocity of 7.52 rad/s.

A point rotates about the origin in the xy plane at a constant radius of 0.216 m and angular velocity of 7.52 rad/s. As you know, the projections of this point on the x- and y-axes undergo simple harmonic motion. What is the amplitude of this motion?
