Remaining time: 58:14 (min:sec) Problem 12. (1 point) If a ball is thrown straight up into the air with an initial velocity of 80 ft/s, its height in feet after t seconds is given by y = 80t - 16t. Find the average velocity for the time period begining when t = 2 and lasting (i) 0.1 seconds 46.4 (ii) 0.01 seconds 48 (iii) 0.001 seconds 50 Finally based on the above results, guess what the instantaneous velocity of the ball is when t = 2.
