Question 119148: Solving a science application. Suppose that a ball is thrown upward with an initial velocity of 80 ft/s. (the initial velocity is the speed with which the ball leaves the throwers hand. The spped will then decrease as the ball rises.) If the ball is released at a height of 77ft, the height equation may be written as follows: h= -16t^2+80t+5, round to the nearest hundredth of a second
77= -16t^2+80t+5
