One end of a cord is fixed and a small 0.300 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 è = 15.0°, the speed of the object is 6.20 m/s. At this instant, find each of the following.
(a) the tension in the string
T = N
(b) the tangential and radial components of acceleration
ar = m/s2 inward
at = m/s2 downward tangent to the circle
(c) the total acceleration
atotal = m/s2 inward and below the cord at °
