WILL REWARD MEDAL/ FAN!!! ALSO COMES WITH A FREE OREO AND A CERTIFICATE OF HONOR JUST FOR YOU BECAUSE YOU HAD HELPED ME!!!! :D :D :D Josefina hit a tennis ball into the air with an initial upward velocity of 16 feet per second. The height h in feet of the ball above the ground can be modeled by h= -16t^2 +16h +3, where t is the time in seconds after Josefina hit the tennis ball. Find the time it takes the ball to reach 7 feet above the ground. Please help and show your work and answer all my questions the best you could in order to receive one GOLDEN Oreo in addition to your rewards. :D
