A body moves s metres in a time t seconds so that s = t3 – 3t2 + 8. Find:
aleksandr82 [10.1K]

Answer is<em> </em><em><u>3t²-6t</u></em>

<h3>Step-by-step Explanation:-</h3>

s(t) =  {t}^{3} - 3 {t}^{2} + 8

Now we need to find velocity. The velocity is the first derivative of position, so let's find the derivative of s(t) :-

s'(t) = v(t) = 3 {t}^{3 - 1} - 3 \times 2 {t}^{2 - 1}

So,

v(t) = 3 {t}^{2} - 6t

Therefore, <u>v(t) = 3t²-6t</u>
