SUMMARY
The power of a machine performing 1800 N-m of work per minute is calculated using the formula for power, which is work divided by time. Since 1 N-m is equivalent to 1 Joule, the total work done in one minute is 1800 Joules. To find power in Watts, divide the total work by the time in seconds (60 seconds), resulting in a power output of 30 Watts.
