To find the final speed and the displacement of the automobile after 5 seconds, we can use the following kinematic equations:
1. **Final velocity \( v \)**:
\[
v = u + a t
\]
where:
\( u \) = initial speed (4.30 m/s)
\( a \) = acceleration (3.00 m/s²)
\( t \) = time (5 s)
2. **Displacement \( s \)**:
\[
s = ut + \frac{1}{2} a t^2
\]
Now, let's calculate the final speed:
