27-30 Circular Motion The position of an object in circular motion is modeled by the given parametric equations. Describe the path of the object by stating the radius of the circle, the posi- tion at time 1 = 0, the orientation of the motion (clockwise or counterclockwise), and the timer that it takes to complete one revolution around the circle. -27. x 3 cost, y = 3 sin = 1 29. x sin 2t, y = cos 21 28. x2 sint, y = 2 cost 30. x 4 cos 31. y = 4 sin 31
