    A firecracker shoots up from a hill 150 feet high, with an initial speed of 110 feet per second. Using the formula H(t) = −16t2 + vt + s, approximately how long will it take the firecracker to hit the ground? Eight seconds Nine seconds 10 seconds 11 seconds

    you know that when the ball hits the ground the height is 0, however you have some missing parts of your equation using the initial values they give you the height at t=0 is 150 [h(0)=150] and plugging into the equation you should get s
