Understanding the Concepts

* Work: Work is done when a force causes an object to move a certain distance. It's calculated as:

* Work (W) = Force (F) x Distance (d)

* Force: The force applied is the weight of the barbell, which is 480 N.

* Distance: The distance the barbell is lifted is 1.6 m.

Calculation

1. Plug in the values: W = 480 N * 1.6 m

2. Calculate: W = 768 J (Joules)

Answer: The work done in lifting the barbell is 768 Joules.
