If an object is propelled upward from a height of s feet at an initial velocity of v feet per second, then its

height h after t seconds is given by the equation

H=−16t^2+vt+s. H is in feet. If the object is propelled from a height of 88 feet with an initial velocity of 96 feet per second, its height h is given by the equation

h=minus−16t^2+96t+88.
