Question

You carry a 20. N bag of dog food up a 6.0 m flight of stairs. How much work was done?

Answer 1

• Force=20N
• Displacement=6m

Work done=Force×Displacement

`\\ \rm\longmapsto Work\:done=20(6)`

`\\ \rm\longmapsto Work\:done=120J`

Answer 2

Solution given:

force=20N

distance travelled=6m

work done=force *displacement=20*6=120joule

Work done=120joule.
