Answer:

#=>W = 1920 " J"#

Explanation:

Work is simply force applied for some distance.

In this case, we are moving #24 " kg"# vertically agains gravity, so we need to overcome the weight of the object. Assuming the gravitational acceleration is #10 " ms"^-2#.

#F = mg = 24(10) = 240 " N"#

The distance moved is #8 " m"#. The work done is therefore:

#W = Fx = 240(8) = 1920 " J"#
