The height of a golfball hit off a 128-foot hill is modeled by the function h(t) = -16*t^2 + 32t + 128,where his height in feet and t is time in seconds. Find the time the golfball takes to reach the ground
+36916 When the ball hits the ground h = 0
0 = -16t^2+32t+128 Use quadratic formula to find t values....throw out negative value...
