If a ball is thrown straight up into the air with an intial velocity of $$ ft/s, its height in feet after $$ seconds is given by $$. Find the average velocity (in ft/s) for the time period beginning with $$ and lasting $$ seconds $$ seconds $$ seconds Finally, based on the above results, guess what the instantaneous velocity of the ball is (in ft/s) when $$.
