<PRE><B>Question 887077</B>
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].
 Please show me your work in this problem, Thank you!
-------------
Average Velocity = [s(1.1)-s(1)]/[1.1-1]
===
= [2.25(1.1^2) - 2.25(1^2)]/[0.1]
----
= [2.25(0.21)]/0.1
-----
= 4.725
