hola!
we know the potential energy formula.
potential energy = m × g × h.
Given are :
mass = 40kg, height of the tower = 72 m and acceleration due to gravity on earth = 9.8
potential energy = 40 × 9.8 × 72.
potential energy = 28,224 joules

Work done will he 0 Joules.
Because,
Work Done =
Force * Cos (Angle) * Displacement
Now,
40 * 9.8 * Cos 90° * 72
As Cos 90° = 0 Joules.
Result will be 0
