Final answer:

The race car's acceleration is 17.34 m/s², calculated using the kinematic equation for motion based on the final velocity, initial velocity, and displacement.

Step-by-step explanation:

To calculate the acceleration of a race car that changes velocity from 0.0 m/s to 51.0 m/s over a displacement of 75.0 m, we can use the kinematic equation:

\(v^2 = u^2 + 2as\)

Where:

\(v\) is the final velocity (51.0 m/s)

\(u\) is the initial velocity (0.0 m/s)

\(a\) is the acceleration

\(s\) is the displacement (75.0 m)

We first rearrange the equation to solve for \(a\):

\(a = \frac{v^2 - u^2}{2s}\)

Now substituting in the values given:

\(a = \frac{51.0^2 - 0.0^2}{2*75.0}\)

\(a = \frac{2601}{150}\)

\(a = 17.34 m/s^2\)

The car's acceleration is 17.34 m/s2.
