work done = force × distance travelled in the direction of the force
Force= 2(9.81) = 19.62N
WD= 19.62×130= 2550.6Nm

Work done to lift the mass is given by

W = mgH

here we know that

m = mass = 2 kg

g = acceleration due to gravity = 9.8

H = height = 130 m

now using the above equation we can write

[tex]U = 2* 9.8 * 130[/tex]

[tex]U = 2548 J[/tex]

so the energy required to do the work is 2548 J
