ball weighing 1 pound is thrown vertically upward from a point 6 ft above the surface of the earth with an initial velocity of 18 ft/sec. As it rises it is acted upon by air resistance that is numerically equal to (1/16)*v (in pounds) where v is the velocity (in feet per second). How high will the ball rise? NOTE: Before you attempt to answer, please take into consideration that this problem is for a Differential Equations class (NOT A...
