One end of a cord is fixed and a small 0.550-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 2.50 m, as shown in the figure below. When 6 = 30.0, the speed of the object is 6.00 m/s. V? I (D (a) At this instant, find the magnitude of the tension in the string. :l N (b) At this instant, find the tangential and radial components of acceleration. a, =:] m/s2 downward tangent to the circle (c) At this instant, find the total acceleration. :] inward and below the cord at :] (d) Is your answer changed if the object is swinging down toward its lowest point instead of swinging up? 0 Yes ONo
