Problem

A cyclist and bicycle together have a mass of 75\,kg. Starting at constant speed, the cyclist rides up a hill gaining 120\,m in elevation in 6.0\,min while air resistance does

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

of work against the motion. What is the cyclist’s average power output for the climb? a)

1.5\times10^{3}\,\text{W}

3.3\times10^{2}\,\text{W}

2.4\times10^{2}\,\text{W}

1.6\times10^{2}\,\text{W}
