The equation y = -16t^2 + 26t + 105 describes the height (in feet) of a ball tossed up in the air at 26 feet per second from a height of 105 feet above the ground. In how many seconds will the ball hit the ground? Express your answer as a decimal rounded to the nearest tenth.

When ball hits the ground   y = height = 0

 

0 = -16t^2 + 26t + 105      Use quadratic formula to find the 't' values....throw out the negative one
