One end of a cord is fixed and a small 0.270-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 θ = 18.0°, the speed of the object is 6.80 m/s.
(a) At this instant, find the tension in the string.
(b) At this instant, find the tangential and radial components of acceleration.
(c) At this instant, find the total acceleration.
(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).
I got 21.14 N for (a) and 18.50 m/s^2 for the radial/centripetal acceleration in (b). I just don't know how to figure out the tangential acceleration. If I could get that, I can solve (c) also. Please help!

It's actually 7.643 N for (a) and 18.5 m/s^2 for centripetal acceleration in (b). Please help with the 2nd part!
