  11. Projectile Motion A baseball is hit straight up with an initial velocity of v0= 80feet per second (or about55 miles per hour) and leaves the bat with an initial height of h0= 3 feet, Find the maximum height of the baseball. Because a is negative, the vertex is the highest point on the graph, with a t-coordinate of The height is: The vertex is at (2.5, 103). The maximum height of the baseball is 103 feet after 2.5 seconds.
