A balloon filled with helium is being releases from the ground and is flying 17 points upward at a rate of 20 feet per second. An archer is challenged to shoot an arrow at the ballon and pop it. If the archer fires the arrow at an initial vertical velocity of 48 feet per second from an initial height of 6 feet, it is modeled by the equation h(t)=-16t^2-48t+6. At what time(s) could the arrow pop the ballon? Round to the nearest hundredth: > X = 20 x = 1.94 x = 3.67
