  • b I shall assume free fall. If we neglect air resistance, the height is given by the formula: y(t) = -1/2 (g * t²) where y(t): is the altitude with respect to time (m). t: is time elapsed (s). g: is the acceleration due to gravity (9.81 m/s² near the surface of the earth). Source and further information: http://en.wikipedia.org/wiki/Free_fall#Without_air_resistance y(8) = -1/2 (9.81 * 8²) = 313.92 m
