Work done by hi

should be 12000Nm i'm pretty sure

Damion Mckinney · Answer 2

mass=60kg

h=20m

g=10m/s²

here the work done by the body is equal to its potential energy

work done=P. E.

As we know that P. E.=mgh

putting values

P. E.=60kg*20m*10m/s²

P. E.=1200kgm*10m/s²

P. E.=12000Nm

so the work done by the body is 12000Nm
