How much work is done against gravity in lifting a 5 kg box of school supplies through a vertical distance of 1.5 m? a) 73.5 J b) 98.1 J c) 49.05 J d) 147.15 J

Answer :

Final answer:

The work done against gravity in lifting the box is approximately 73.5 J.

Explanation:

To calculate the work done against gravity, we need to use the formula:

Work = Force × Distance × cos(angle)

In this case, the force is the weight of the box, which can be calculated using the formula:

Force = mass × acceleration due to gravity

So, the work done against gravity is:

Work = (5 kg) × (9.8 m/s^2) × (1.5 m) × cos(180°)

Simplifying this equation gives us:

Work ≈ 73.5 J
