If a ball is thrown straight up into the air with an initial velocity of 95 ft/s, its height in feet after t second is given by y=95t−16t2. find the average velocity for the time period beginning when t=1 and lasting(i) 01 seconds: (ii) 001 seconds: (iii) 0001 seconds: finally based on the above results, guess what the instantaneous velocity of the ball is when t=1.
