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 3.0×104 J3.0\times10^{4}\,\text{J} of work against the motion. What is the cyclist’s average power output for the climb? (a) 1.5×103 W1.5\times10^{3}\,\text{W} (b) 3.3×102 W3.3\times10^{2}\,\text{W} (c) 2.4×102 W2.4\times10^{2}\,\text{W} (d) 1.6×102 W1.6\times10^{2}\,\text{W}
