A 0.50 kg mass attached to a string moves in a vertical circle of radius 1.2 m. At the bottom of the circle, its speed is 7.0 m/s. (a) Determine the tension at the bottom of the circle. (b) Using conservation of energy, determine the speed at the top. (c) Determine the tension at the top. (d) Explain why the tension is smaller at the top.

A 34-yeаr-оld pаtient fаlls оntо an outstretched hand and presents with lateral elbow pain, swelling, and inability to fully extend the elbow. Initial radiographs do not show a clearly displaced fracture, but the report notes an elbow joint effusion/posterior fat pad sign. What is the most appropriate interpretation?
