6. The world's highest bridge, the Malou Vuaduct in France, is 1125 feet above the River Tam.An object dropped from the top of this bridge.Neglecting air resistance, the height of the object at times t seconds is given by polynomial function P (t) = -16t² + 1125.Find the height of the object when t= 1 seconds and when t = 8 seconds. _______​
