To calculate the final speed after 5.0 seconds, you need to know the car's acceleration. Assuming constant acceleration, you can use the formula:
\[ \text{Final speed} = \text{Initial speed} + (\text{Acceleration} \times \text{Time}) \]
Given the car's acceleration is \( \frac{60 \, \text{mph}}{8.0 \, \text{s}} \), and the initial speed is 50 mph, you can substitute these values into the formula to find the final speed after 5.0 seconds.
