2. A baseball player throws a ball into the air with an initial vertical velocity of 10 feet per second. The ball is released at a height of 6 feet. Use the model of h =- - 16t? + 40t + 6, where h is the height of the ball and t is the time in seconds after the ball is released from the baseball players hand to find the following. a. What is the maximum height of the ball (the y value of the vertex)?

b. Use the quadratic equation to find the time that the ball is in the air.​
