What is the work required to lift a 10 kg box off the ground to a height of
5.0 m?

490J

Explanation:

Given parameters:

Mass of box  = 10kg

Height  = 5m

Unknown:

Work done  = ?

Solution:

Work done can be derived from the product of force and distance;

   Work done = force x distance

 Force here is applied by gravity and it is the weight

 The distance is the height

  Work done  = weight x height

 Work done  = mass x acceleration due to gravity x height

 Work done  = 10 x 9.8 x 5  = 490J
