Problem

During a

20\,\text{s}

sprint, a cyclist’s power output is recorded at

5\,\text{s}

intervals: 0–5 s:

200\,\text{W}

5–10 s:

220\,\text{W}

10–15 s:

240\,\text{W}

15–20 s:

260\,\text{W}

Assuming the power is constant within each interval, determine the total mechanical work done by the cyclist over the entire

20\,\text{s}

sprint.
