MODELING WITH MATHEMATICS The polynomial $-16t^2+v_0t+s_0$ represents the height (in feet) of an object, where $v_0$ is the initial vertical velocity (in feet per second), $s_0$ is the initial height of the object (in feet), and $t$ is the time (in seconds). Write a polynomial that represents the height of the object. Then find the height of the object after 1 second.
