Question 887067
The distance traveled by a ball rolling down a ramp is given by s(t)=2.25t^2, where t is the time in seconds after the ball is released, and s(t) is measured in feet.  Evaluate the average velocity of the ball for the time interval 
[1.0, 1.1]
--------------
Find the distance s(1.1)
Subtract the distance s(1) from it.
avg speed = (s(1.1) - s(1))/(1.1 - 1.0) ft/sec
