#100# watts

Explanation:

Power is defined by the equation,

#P=W/t#

  • #W# is the work done in joules

  • #t# is the time taken in seconds

Work done is defined through the equation,

#W=F*d#

  • #F# is the force in newtons

  • #d# is the distance moved in meters

So, work done is:

#W=100 \ "N"*100 \ "m"#

#=10,000 \ "J"#

Therefore, the power exerted is:

#P=(10,000 \ "J")/(100 \ "s")#

#=100 \ "W"#
