You fire a rifle straight up. Your bullet leaves your gun at a velocity of 928 feet per second. Ignore air resistance. Consider the muzzle of your gun to be at height zero. The bullet will reach its maximum altitude of _______ feet after ______ seconds.
I know in order to find time I have so far with the equation....
h(t) = -16t^2+928t but thats as far as I got. I'm not sure how to do the rest. I tried the quadratic equation using just that and it didn't work. I got 58 or 57 point something and the answer is wrong. The teacher just said we had to solve this using a quadratic equation.
