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 = 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 = .
Your response differs from the correct answer by more than 10%. Double check your calculations.m/s2 inward and below the cord at

(d) Is your answer changed if the object is swinging up instead of swinging down?
