A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 33 ft/s. Its height in feet after t seconds is given by y = 33r - 251². A. Find the average velocity (include units help (units)) for the time period beginning when t = 3 and lasting .01 s: -754.5ft/s² .005 s: -754.6ft/s² .002 s: -754.5ft/s² .001 s: -754.5ft/s² NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator. B. Estimate the instantaneous velocity when t = 3 (include units help (units)). Answer: -117ft/s
