A bullet is fired straight up from a BB gun with initial velocity (v0) of 1,120 feet per second at an initial height of 8 feet. Use the formula h=â’16t2 v0t 8 to determine how many seconds it will take for the bullet to hit the ground. That is, when will h=0? Round your answer to the nearest whole number.
