At a certain instant, point A is a distance = 135 mm from the central point of oscillation, with an acceleration of 1.35 m/s². Analyze the motion and then calculate: The frequency of oscillation is f = Hz • The period of motion of the point is tp = sec • The speed of point A when it is at the central point is v, = m/s • The acceleration of point A when it is at the central point is ao = m/s? • The speed of point A at when it is the furthest away from the central point is vm = m/s
