Explanation:
The question is incomplete as the value of s(t) is missing;
However, the following explanation will guide you;
I'll continue my explanation with the following assumption that:
Required
Determine the velocity at t = 8
To do this; first calculate s(t) by substituting 8 for t in
Next, is to calculate the velocity by dividing s(t) by t where t = 8
i.e.
Substitute 8 for t
Substitute 72 for s(8)
<em>So: all you need to do is first calculate s(8), then divide the resulting value by 8 to get your result</em>
