Final answer:

The work done by a bodybuilder lifting a 95kg mass through a distance of 1.6m can be calculated using the formula W = mgd, which involves multiplying the weight of the mass by the distance lifted.

Step-by-step explanation:

The question asks to calculate the work done on a mass when a bodybuilder lifts it through a certain distance. Work done is a physical concept that combines force and displacement and is taught within high school Physics curriculum.

Work done (W) is defined as the force (F) applied to an object times the distance (d) through which the object moves, mathematically expressed as W = F × d. Since the force here is due to gravity, it is the weight of the object (mg, where m is mass and g is the acceleration due to gravity). For the bodybuilder lifting a mass of 95kg through a height of 1.6m, we use the formula W = mgd to calculate the work done.

Assuming the standard acceleration due to gravity of approximately 9.8 m/s2, the work done can be calculated as follows:

  1. Calculate the weight of the mass: Weight (mg) = 95 kg × 9.8 m/s2
  2. Multiply the weight by the distance lifted: Work done (W) = Weight × Distance = (95 kg × 9.8 m/s2) × 1.6 m
  3. Perform the calculations to find the total work.

Using these steps, the work done by the bodybuilder can be found, which is an essential concept in understanding energy transfer and mechanical work in Physics.
