Calculate the work done when the load of 100 kg lifted by 5 metre

Open in App

Solution

Dear student
Mass (m) = 100 kg Displacement (s) = 5 m g = 9.8 m/s2 Force acting downwards on mass 5 kg is = Mg F = Mg => F=100×9.8 = 980 N We know Work done = F×s Thus work done to lift the mass up by 5 m will be = 980×5 = 4900 Joules
