A car of mass \( m \) starts from rest and accelerates so that the instantaneous power delivered to the car has a constant magnitude \( \mathrm{P}_{0} \). The instantaneous velocity of this car is proportional to
a. \( \mathrm{t}^{2} \mathrm{P}_{0} \)
b. \( t^{1 / 2} \)
c. \( t^{-1 / 2} \)
d. \( \frac{t}{\sqrt{m}} \)
