Answer:

Approximately #549# joules.

Explanation:

Work done is given by the equation,

#W=F*d#

where:

  • #W# is the work done in joules

  • #F# is the force exerted in newtons

  • #d# is the distance moved in meters

Here, the force is the weight's weight in newtons, which is #14 \ "kg"*9.8 \ "m/s"^2=137.2 \ "N"#.

Therefore, the work done is:

#W=137.2 \ "N"*4 \ "m"#

#=548.8 \ "J"#
