Find the average velocity of the gum on the interval 2<t<3 and 2<t,2.1

Question

the height of the gum can be given by the mathematical model: h=65-4.9t^2

Answer 1

Velocity is a rate...distance/time

 

To find the average velocity over an interval, find the height of the gum at the endpoints of the interval and then divide by the length of the interval.

 

( h(3) - h(2) ) / (3-2)
