Answer
The final velocity can be calculated using the following equation of motion:<br /><br />v = u + at<br /><br />Where:<br /><br />* v = final velocity<br />* u = initial velocity<br />* a = acceleration<br />* t = time<br /><br />In this case:<br /><br />* u = +8 m/s<br />* a = +2 m/s²<br />* t = 5 s<br /><br />Substituting these values into the equation:<br /><br />v = 8 m/s + (2 m/s²)(5 s)<br />v = 8 m/s + 10 m/s<br />v = 18 m/s<br /><br />So the cyclist's final velocity is $\boxed{+18m/s}$.<br />
