Step-by-step Solution
To find the first and second derivatives of the function
\[
s = \frac{t^{5} + 3t^{4} - 4}{t^{5}},
\]
we can first simplify the expression. We can rewrite \( s \) as follows:
\[
s = \frac{t^{5}}{t^{5}} + \frac{3t^{4}}{t^{5}} - \frac{4}{t^{5}} = 1 + \frac{3}{t} - \frac{4}{t^{5}}.
\]
Now, we can differentiate \( s \) with respect to \( t \).
### First Derivative
Using the power rule and the derivative of \( t^{-n} \):
\[
s = 1 + 3t^{-1} - 4t^{-5}.
\]
Now, we differentiate term by term:
1. The derivative of \( 1 \) is \( 0 \).
2. The derivative of \( 3t^{-1} \) is \( -3t^{-2} \).
3. The derivative of \( -4t^{-5} \) is \( 20t^{-6} \).
Putting it all together, we have:
\[
\frac{ds}{dt} = 0 - 3t^{-2} + 20t^{-6} = -\frac{3}{t^{2}} + \frac{20}{t^{6}}.
\]
### Second Derivative
Now, we differentiate \( \frac{ds}{dt} \) to find the second derivative:
\[
\frac{ds}{dt} = -3t^{-2} + 20t^{-6}.
\]
Differentiating term by term again:
1. The derivative of \( -3t^{-2} \) is \( 6t^{-3} \).
2. The derivative of \( 20t^{-6} \) is \( -120t^{-7} \).
Thus, the second derivative is:
\[
\frac{d^2s}{dt^2} = 6t^{-3} - 120t^{-7} = \frac{6}{t^{3}} - \frac{120}{t^{7}}.
\]
### Summary
The first and second derivatives of the function \( s \) are:
\[
\frac{ds}{dt} = -\frac{3}{t^{2}} + \frac{20}{t^{6}},
\]
\[
\frac{d^2s}{dt^2} = \frac{6}{t^{3}} - \frac{120}{t^{7}}.
\]
Quick Answer
The first derivative is \( \frac{ds}{dt} = -\frac{3}{t^{2}} + \frac{20}{t^{6}} \) and the second derivative is \( \frac{d^2s}{dt^2} = \frac{6}{t^{3}} - \frac{120}{t^{7}} \).
