if an object is thrown vertically upward with an initial velocity of v, from an original position of s, the height h at any time t is given by: h=-16t^2+vt+s (where h and s are in ft, t is in seconds and v is in ft/sec)

A ball is thrown upward with an initial velocity of 96 ft/sec from the top of a 100ft bridge. Determine the time that it takes for the ball to get to a height of 200ft.
