Final answer:

The final velocity of the car after 8 seconds of accelerating at 5.0 m/s² from an initial velocity of 75 m/s is 115 m/s.

Step-by-step explanation:

A car going 75 m/s undergoes an acceleration of 5.0 m/s2 for 8 seconds. To find the final velocity of the car, we use the formula for acceleration:

final velocity (v) = initial velocity (u) + (acceleration (a) × time (t))

Substituting the given values:

v = 75 m/s + (5.0 m/s2 × 8 s)

v = 75 m/s + 40 m/s

v = 115 m/s

So, the final velocity of the car after 8 seconds is 115 m/s.
