A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 26 ft/s. Its height in feet after $t$ seconds is given by $y=26t-22t^{2}$.

A. Find the average velocity (include units help (units)) 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.

B. Estimate the instantaneous velocity when $t=1$ (include units help (units)).
