A fallen tree if lifted 2.75m.What is the work done?

W=Fd

force=mass*g mass is not given

So this question cannot be solved?

it requires the weight of the tree.

To determine the work done on lifting a fallen tree, we need to know the force applied and the distance over which the force is applied.

Given:
Distance (d) = 2.75 meters

The force required to lift the tree should be provided in order to calculate the work done. Work (W) is calculated by multiplying the force (F) by the distance (d).
