end, where it swings in a sect? One end of a cord is fixed and a small 0.430-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 ? = 18.0°, the speed of the object is 4.90 m/s. At this instant, find each of the following.

(a) the tension in the string
T =
Your response differs from the correct answer by more than 10%. Double check your calculations. N
(b) the tangential and radial components of acceleration
ar = _8___m/s2 inward
at = _______ m/s2 downward tangent to the circle
(c) the total acceleration
atotal = m/s2 inward and below the cord at _____°
(d) Is your answer changed if the object is swinging down toward its lowest point instead of swinging up?
Yes
No
(e) Explain your answer to part (d).
