A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 29 ft/s. Its height in feet after t seconds is given by y = 29 t − 23 t 2 . A. Find the average velocity for the time period beginning when t 1 =3 and lasting for the following number of seconds Note: If the time is 2 seconds and lasting for .01 seconds, then your interval is [2, 2.01] .01 sec: .005 sec: .002 sec: .001 sec: NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator. Estimate the instanteneous velocity when t=3.
