In 1990, American Randy Barnes set a world record of 23.11 m in the shot put. In the Men's Shot, a 7.3 kg object (the shot) is thrown for maximum distance. The shot is released from as high of a point as possible, traveling upwards at an angle relative to the horizontal. A) Analyzing the video of the throw, you find that Randy released the shot put at an angle of 38.0 ∘ from a height of 1.80 m above...
