If a ball is thrown straight up into the air with an initial velocity of 55 ft/s, its height in feet after t second is given by y = 55t - 16t2. Find the average velocity (include units, help (units)) for the time period begining when t = 2 seconds
and lasting
(i) 0.5 seconds
Average velocity:
(ii) 0.1 seconds
Average velocity:
-(iii) 0.01 seconds
Average velocity
Finally based on the above results, guess what the instantaneous velocity of the ball is when t = 2.
Average velocity:
