Calculate Work Done and Potential Energy

Work Done Calculation:

Work done is calculated by multiplying the force applied by the distance over which the force is applied. In this case, the force applied to lift the barbell is 500 Newtons, and the distance it is lifted is 2.2 meters.

Given data:

• Force: 500 N
• Distance: 2.2 m

Using the formula for work done:

Work done = Force x Distance

Substitute the values:

Work done = 500 N x 2.2 m = 1100 Joules

Potential Energy Calculation:

When the barbell is lifted to a height of 2.2 meters above the floor, it gains potential energy due to its position in the gravitational field.

The potential energy of an object is given by the formula:

Potential Energy = Mass x Acceleration due to Gravity x Height

Given data:

• Force: 500 N
• Distance: 2.2 m
• Acceleration due to Gravity: 9.81 m/s^2

Now, we need the mass of the barbell to calculate its potential energy.
