One end of a cord is fixed and a small 0.530-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 3.00 m, as shown in the figure below. When ? = 16.0°, the speed of the object is 8.20 m/s.
(a) At this instant, find the tension in the string.
T = N
(b) At this instant, find the tangential and radial components of acceleration.
ar = m/s2 inward
at = m/s2 downward tangent to the circle
(c) At this instant, find the total acceleration.
atotal = m/s2 inward and below the cord at °
