Problem

A water pump runs at an average power output of

2.5\,\text{kW}

for

3.0\,\text{min}

. Neglecting energy losses, how much work does the pump do on the water during this interval? a)

7.5\times10^{4}\,\text{J}

4.5\times10^{6}\,\text{J}

4.5\times10^{5}\,\text{J}

7.5\times10^{5}\,\text{J}
