A runner of mass 57.5 kg starts from rest and accelerates with a constant acceleration of $1.25 \mathrm{~m} / \mathrm{s}^{2}$ until she reaches a velocity of $6.3 \mathrm{~m} / \mathrm{s}$. She then continues running with this constant velocity. a) How far has she run after 59.7 s? b) What is the velocity of the runner at this point?
