ater during that same golf outing Marc decided to show off by trying to hit the green in one shot. He said he hit the green as the ball hung in the air for at least 15 seconds. The formula for this shot is h(x) = -16xsquared +248x. How can Marc provide proof that his shot actually hung in the air for 15 seconds?

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
