On August 24, 1894, Pop Shriver of the Chicago White Stockings caught a baseball dropped (by Clark Griffith) from the top of the Washington Monument. The Washington Monument is 555 ft tall and a baseball weighs 5 1/8 oz.
(a) If we ignore air resistance and assume the baseball was acted upon only by gravity, how fast would the baseball have been traveling when it was 7 ft above the ground?
(b) Suppose we now include air resistance in our model, assuming that the drag force is proportional to velocity with a drag coefficient k = 0.0018 lb-sec/ft. How fast is the baseball traveling in this case when it is 7 ft above the ground.
