PLEASE HELP Zane has built a large firework type rocket to shoot off north table mountain. Zane wants to know the height the rocket will reach and the time until the rocket hits the ground. he knows the force of gravity is -10m/sec^2, the initial velocity of the rocket is 50m/s and the height of north table mountain is 400 meters. he also knows the rocket flight will be parabolic which can be modeled by a quadratic function. What's the quadratic function in standard form? And how many seconds till it hits the ground?
