If a ball is thrown into the air with a velocity of 40ft/s, its height in feet after "t" seconds is given by y = 40t-16t^2.
a) Find the average velocity for the time period beginning when t=2 and lasting
(i) 0.5 seconds
(ii) 0.1 second
(iii) 0.05 seconds
(iv) 0.01 second
b) Find the instantaneous velocity when t=2.
Splution calculates Average Velocity & Instantaneous Velocity for a ball is thrown into the air.
