1. (Parabola) A ball is thrown in the air with an initial vertical velocity of 42 feet per second, from an initial height of 6 feet. The ball's height, h (in feet), at time t (seconds), can be modeled by the quadratic function h = -16t^2 + vt + s. Remember from your notes that is the initial velocity and s is the starting height. How long is the ball in the air? Does the ball reach a height of 36 feet?
