A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 31 ft/s. Its height in feet after t seconds is given by y = 31t - 18t.

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.

B. Estimate the instantaneous velocity when t=1.

Please show all work. Thank You.
