A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 43 ft/s. Its height
in feet after t seconds is given byy=43t-23t^{2}. A. Find the average velocity for the time period beginning when t=1 and lasting
.01 s:
.005 s:
.002 s:
.001 s:
NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator.
