Suppose that the math man, a super hero that fights crime with math and physics, can decelerate the rate of gravity. during a recent fight with a diamond thief, math man fell from the top of a 500 meter building. the equation d = t² x 0.25 describes math man's distance from the ground as he falls. how long does math man spend falling if he falls all the way from the top of the building to the ground?
