Problem

1000\,\text{kg}

car is traveling on a straight, level road at

15\,\text{m/s}

when its driver steps on the accelerator. The car’s acceleration immediately becomes

2.0\,\text{m/s}^2

in the forward direction. Ignoring friction and air resistance, what is the instantaneous net power associated with the horizontal net force acting on the car at that instant? a)

1.5 \times 10^{4}\,\text{W}

3.0 \times 10^{4}\,\text{W}

3.2 \times 10^{4}\,\text{W}

2.0 \times 10^{5}\,\text{W}
