1. The problem statement, all variables and given/known data One end of a cord is fixed and a small 0.250 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 = 20.0°, the speed of the object is 7.70 m/s. At this instant, find each of the following. (a) the tension in the string (b) the tangential and radial components of acceleration ar = at = (c) the total acceleration 2. Relevant equations I have been trying to use ar = mgcos(20) at = mgsin(20) Also for the Tension, I was using T= mg(v^2/Rg + cos(20) 3. The attempt at a solution My numbers are not coming out right, and I am afraid I don't no understad this problem in the slightest. Please help me. Thank You.
