The height of a golf ball hit off a 128-foot cliff is modeled by the function h(t) = −16t^2 + 32t + 128, where h is height in feet and t is time in seconds. Find the time the golf ball takes to reach the ground.
+36916 h will = 0 when the ball hits the ground
0 = -16t^2+32t+128 Use quadratic formula of factoring to solve for 't' throw out the negative t value
