Academics

One end of a cord is fixed and a small 0.390-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.00 m as shown in the figure below. When ? = 26.0°, the speed of the object is 7.90 m/s. At this instant, find each of the following.

(a) the tension in the string

(b) the tangential and radial components of acceleration

(c) the total acceleration Is your answer changed if the object is swinging down toward its lowest point instead of swinging up?

(e) Explain your answer to part (d).
