At a time of

*t* seconds, a particle moves a distance of

*s* meters from its starting point, where

*s*=4.2 sin(1.2

*t*).

(a) Find the average velocity (correct to four decimal places) between

*t*=1 and

*t*=1+

*h* for the following values of

*h*.

If

*h*=0.1 then the average velocity over the time period [1,1.1] equals______m/s.

If

*h*=0.01 then the average velocity over the time period [1,1.01] equals______m/s.

If

*h*=0.001 then the average velocity over the time period [1,1.001] equals______m/s.

If

*h*=0.0001 then the average velocity over the time period [1,1.0001] equals_____m/s.

This qusetion confuses me

Do I just substitute the 1,1.1 into x and solve it? Any help/hints are greatly appreaciated thanks a lot !!
