A golfer hits a ball from a starting elevation of 7 feet with a velocity of 70 feet per second down to a green

with an elevation of -2 feet. The number of seconds t it takes the ball to hit the green can be represented

by the equation - 16t2 + 70t +7=-2. How long does it take the ball to land on the green?

It takes the ball ___

seconds to land on the green.
