One end of a cord is fixed and a small 0.610 kg object is attached to the other end, where it swings in a section of a vertical circle of radius 3.00 m. When as shown in the figure, the speed of the object is 7.40 m/s. At this instant,
(a) What is the tension in the string?
(b) What are the radial and tangential component of the acceleration?
