  • Mass=m=60kg
  • Acceleration due to gravity=g=10m/s^2
  • Distance=d=12m
  • Force=F
  • Work done=W

Applying Newton's law


\\ \sf\longmapsto F=mg


\\ \sf\longmapsto F=60(10)


\\ \sf\longmapsto F=600N

Now


\\ \sf\longmapsto W=Fd


\\ \sf\longmapsto W=600(12)


\\ \sf\longmapsto W=7200J

  • Positive work done
