SUMMARY
The runner accelerates at 1.7 m/s² for 4.8 seconds, resulting in a final speed at the end of the race. The calculation involves using the formula for final velocity under constant acceleration, which is v = u + at, where u is the initial velocity (0 m/s), a is the acceleration (1.7 m/s²), and t is the time (4.8 seconds). The final speed of the runner at the end of the race is 8.16 m/s, as the runner maintains this speed after acceleration ceases.
