The displacement (in feet) of a certain particle moving in a straight line is given s=t^3/8 by where t is measured in seconds. Find the average velocity over the interval (1, 1.8)

Avg   velocity  is

 

[ s(8)    - s(1)  ]   /  [  8  - 1  ]

 

So we have

 

[ 8^3 / 8    -    1^3/8   ]   /   7   =

 

[64  -  1/8] / 7   =

 

73/8  ft / s       =    9.125   ft / s
