A car travels on a straight horizontal road. Its kinetic energy is $1.6\,\text{MJ}$. The car then accelerates for $20\,\text{s}$, during which the car’s kinetic energy rises to $2.5\,\text{MJ}$. What is the minimum average power developed by the car engine for this acceleration?
- A$45\,\text{W}$
- B$205\,\text{W}$
- C$45\,\text{kW}$
- D$205\,\text{kW}$
