What is the minimum time needed to lift a 2000-N weight 10 meters using a motor with a maximum power rating of 8000 watts?
2.5 seconds. Here's how: Multiply the weight by the height change to determine the amount of work necessary: (2000 N)(10 M) = 20000 Newton meters, or 20000 Joules. Divide this by the power of 8000 Joules/sec to determine time of (20000 J) / (8000 J/s) = 2.5 seconds. If less than 8000 watts is used, then the denominator is smaller, so the time is longer.
