What is the average power output pf a weight lifter who can lift 250 kg 2.0 m in 2.0 s

The average power output of the weight lifter who can lift the given mass is 2450 Watts.

Given the data in the question;

Power is the amount of energy transferred per unit time. It is expressed as:

Where W is work done and t is elapsed time.

So, we find the work done

Work done = Force × Displacement

Since Force = Weight = m × g

Where g is acceleration due to gravity ( )

Hence

We substitute our value into the previous equation

Therefore, the average power output of the weight lifter who can lift the given mass is 2450 Watts.

Power = 2.45Kw or 2450 Watts.

Explanation:

Given the following data;

Mass, m = 250kg

Height, h = 2m

Time, t = 2secs

We know that acceleration due to gravity, g is equal to 9.8m/s²

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

But Energy = mgh

Substituting into the equation, we have

Power = 2450 Watts

To convert to kilowatt (Kw), we would divide by 1000

Power = 2450/1000

Power = 2.45Kw.

Therefore, the average power output of the weightlifter is 2.45 Kilowatts.
