One end of a cord is fixed and a small 0.550-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 ? = 17.0°, the speed of the object is 5.30 m/s. At this instant, find each of the following.
the tangential and radial components of acceleration:?
total acceleration:? inward and below the cord at degrees
