Answer

This equates to approximately 1.5 meters. This value represents the height to which the athlete lifts the weight.

Explanation

This problem involves principles of physics specifically related to the concept of work, force, and distance. From the provided variables, 420 J is the work done in lifting the weight, and 280 N is the force applied to accomplish this lift. The aim is to solve for the distance (or height) to which the weight is lifted, given the equation "Work = Force x Distance".We can solve for Distance by transposing the equation as follows: Distance = Work / Force.By substitifying the given values into this equation, we will have:Distance= 420 J / 280 N
