If a ball is thrown straight up into the air with an initial velocity of 40 ft/s, it height in feet after t second is given by y=40t−16t2. find the average velocity for the time period begining when t=2 and lasting
(i) 0.5 seconds
(ii) 0.1 seconds
(iii) 0.01 seconds
finally based on the above results, guess what the instantaneous velocity of the ball is when t=2.
