Calculate the amount of work done in lifting a body of mass 3 Kg through a distance of 11 metres.
Asked by Topperlearning User | 15 Apr, 2014, 02:48: PM
answered-by-expert Expert Answer
Work = Force x Distance
Force = Mass x Acceleration due to gravity
           = mg
           = 3 x 9.8
           = 29.4 N
 
Work = F × s
          = 29.4 x 11
          = 323.4 J
