A man wighing 80 kg wt carrice a stone of weight 20kg wt to the top a builling 30 m high .Calculatethe work done by him .Take `g=9.8 ms^(-2)`

A man weighing 70 kg carries a 30 kg box to the top of a building 20 m high. Calculate the work done by the man (take g = 9.8 ms^(-2) ).

A man weighing 70kg carries a weight of 10kg on the top of a tower 100 m high. Calculate the work done by the man. (g = 10m//s^2)

Force is required to lift a body from the ground to a height h and work is measured as the product of force and magnitude of displacement. A man of mass 60 kg carries a stone of mass 20 kg to the top of a multistoreyed building of height 50 m . Calculate the total energy spent by him? (g= 9.8 m/s^2)

A load of 100 kg is pulled up by 5 m. Calculate the work done. ( g = 9.8 m//s^(2) )

A gardener pushes a lawn roller through a distance of 20m. If he applies a force of 20 kg wt in a direction inclined at 60^(@) to the grounds, find the work done by him. Take g=9.8ms^(-2) .

A load of 100 kg is pulled upwards by 5 m. Calculate the work done. [g = 9.8 m//s^(2)]
