1.2\times10^{3}\,\text{kg}

car travels up a straight

150\,\text{m}

stretch of road that rises at a constant

5.0^{\circ}

above the horizontal. During this time the car accelerates uniformly from

15\,\text{m}\!/\!\text{s}

25\,\text{m}\!/\!\text{s}

12\,\text{s}

. Neglecting resistive forces, determine the average power produced by the car’s engine over the

12\,\text{s}

interval.
