The equation y = -16t^2 + 60t + 54 describes the height (in feet) of a ball thrown upward at 60 feet per second from a height of 54 feet from the ground, where represents time, measured in seconds. In how many seconds will the ball hit the ground? Express your answer as a decimal rounded to the nearest hundredth.
+36914 When the ball hits the ground, the height, y = 0
-16t^2+60t+54 = 0 use quadratic formula or factoring to solve for 't' ..... throw out the negative value....
