The movers put out a power of 1635 Watts, or 1.635 kilowatts, when carrying a 1000 kg refrigerator downstairs over 10 meters in 60 seconds, assuming realistic gravitational acceleration.
The question involves calculating the power output required to move an object, which is a topic in physics. In the given scenario, movers are carrying a 1000 kg refrigerator downstairs over a distance of 10 meters with an acceleration of 25 m/s2 in 60 seconds. To determine how much power they put out, we should first calculate the work done on the refrigerator and then divide it by the time taken to find the power.
However, the acceleration provided in the question is extremely high and not typically associated with movers carrying an object downstairs. As such, there may be a typo in the question. Assuming a more realistic scenario where acceleration due to gravity (9.81 m/s2) is the only acceleration acting on the refrigerator, the movers are doing work against gravity. This can be calculated using the formula Work = force x distance, with force being the weight of the refrigerator (mass x acceleration due to gravity). Then, the power can be calculated using the formula Power = Work / time.
Work = (mass x gravity) x distance = (1000 kg x 9.81 m/s2) x 10 m = 98100 Joules
Power = Work / time = 98100 J / 60 s = 1635 Watts
The movers therefore put out a power of 1635 Watts, or 1.635 kilowatts.
