Calculation of Work Done

To calculate the work done by the weightlifter, we can use the formula:

Work = Force × Distance

In this case, the force is equal to the weight of the dumbbell, which is 24 kg. The distance is the height to which the weight is lifted, which is 2 meters.

Therefore, the work done by the weightlifter is:

Work = 24 kg × 2 m = 48 joules

So, the weightlifter performs 48 joules of work when lifting the 24 kg dumbbell to a height of 2 meters.

Answer

The weightlifter performs 48 joules of work when lifting the 24 kg dumbbell to a height of 2 meters.
