Question
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 1.50 m. When θ = 19.0°,the speed of the object is 5.50 m/s.
(a) At this instant, find the magnitude of the tension in the string.
N
(b) At this instant, find the tangential and radial components of acceleration.
(c) At this instant, find the total acceleration.
_____ 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?
N
(b) At this instant, find the tangential and radial components of acceleration.
