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=-161 + vt +s (where h and s are in ft, t is in seconds and v is in ft/sec) Solve for t when the object hits the ground. (when h = 0) t = blank 1 + vblank 2 -4(blank 3) 2(-16) Fill in the blanks of the quadratic formula. Enter: blank 1, blank 2, blank 3 (separated by commas).
