One end of a cord is fixed and a small 0.250-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.50 m, as shown in the figure below. When 0 = 26.0, the speed of the object is 6.50 m/s. A (a) At this instant, find the magnitude of the tension in the string. N (b) At this instant, find the tangential and radial components of acceleration. at m/s downward tangent to the circle ac m/s2 inward (c) At this instant, find the total acceleration. inward and below the cord at
