Answer is: ending velocity at the finish line was 20,75 m/s.

v (initial velocity) = 5 m/s.

a = 9 m/s²; acceleration attained by the body.

t = 1,75 s; sprinting time.

Ending velocity is defined as the velocity attained by a body after completing distance at certain time interval:

v (ending velocity) = v (initial velocity) + a·t.

v (ending velocity) = 5 m/s + 9 m/s² · 1,75 s.

v (ending velocity) = 20,75 m/s.
