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>
Answer:
Political appointments are short-lived in order to prevent autocracy, tyranny, and clinging on to power.
Explanation:
Power corrupts and absolute power corrupts absolutely. Humans have a tendency to be intoxicated by power. This is why most political positions run for just a few years after which the people can determine through voting on whether they will continue with the appointee or elect another person. The presidential and senatorial sectors of the United States democracy follow this system.
Presidents are allowed 4 years in office after which another election is conducted to determine their remaining or being removed. This prevents tyranny and the imposition of the opinions of a few against the majority.
