A bullet is fired straight up from a gun with initial velocity 1120 feet per second at an initial height of 8 feet. Use the formula h=−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 2 decimal places.

Answer 1

0 = -16 t^2 + 1120 t + 8

0 = -2 t^2 + 140 t + 1

use the quadratic formula to find t
