Suppose that a baseball is tossed up into the air at an initial velocity 1818\text{ m/s} m/s. The height of the baseball at time tt in seconds is given by h\mathopen{}\mathclose{\left(t\righ t)}=18 t-4.9 t^{2}h(t)=18t−4.9t 2 (in meters). a) What is the average velocity for \left[1, 1.5\right][1,1.5]?
