Solution Steps

Step 1: Find the velocity function \( v(t) \)

To find the acceleration function \( a(t) \), we first need to determine the velocity function \( v(t) \). The velocity is the derivative of the position function \( s(t) \).

Given: \[ s(t) = 2t^{4} - 2t^{3} - 2t^{2} - 8 \]

Compute the derivative of \( s(t) \) with respect to \( t \): \[ v(t) = \frac{ds}{dt} = \frac{d}{dt}(2t^{4}) - \frac{d}{dt}(2t^{3}) - \frac{d}{dt}(2t^{2}) - \frac{d}{dt}(8) \]

Using the power rule for differentiation: \[ v(t) = 8t^{3} - 6t^{2} - 4t \]

Step 2: Find the acceleration function \( a(t) \)

The acceleration function \( a(t) \) is the derivative of the velocity function \( v(t) \).

Given: \[ v(t) = 8t^{3} - 6t^{2} - 4t \]

Compute the derivative of \( v(t) \) with respect to \( t \): \[ a(t) = \frac{dv}{dt} = \frac{d}{dt}(8t^{3}) - \frac{d}{dt}(6t^{2}) - \frac{d}{dt}(4t) \]

Using the power rule for differentiation: \[ a(t) = 24t^{2} - 12t - 4 \]

Step 3: Write the final acceleration function

The acceleration function \( a(t) \) is: \[ a(t) = 24t^{2} - 12t - 4 \]

\[ a(t) = \boxed{24t^{2} - 12t - 4} \]

Final Answer

\(\boxed{24t^{2} - 12t - 4}\)
