Final answer:

To calculate the average power output of a strongman competitor lifting a 250 kg stone a height of 2.0 m in 2.5 s, we can use the formula: Power = Work/Time. Calculate the force applied using Newton's second law, F = m × g, where m is the mass of the stone and g is the acceleration due to gravity. Divide the work done by the time taken to find the average power output.

Step-by-step explanation:

To calculate the average power output of a strongman competitor lifting a 250 kg stone a height of 2.0 m in 2.5 s, we can use the formula:



Power = Work/Time



First, let's calculate the work done by the competitor, which is the product of the force applied and the distance moved:



Work = Force × Distance



The force applied can be determined using Newton's second law, F = m × g, where m is the mass of the stone and g is the acceleration due to gravity.

Now we can calculate the average power output by dividing the work done by the time taken:



Average Power = Work / Time



So, substituting in the values, we get:



Average Power = (Force × Distance) / Time



Remember to use proper SI units.
