Work done, W = 68J or 68Nm
Displacement, S = 8m
Force, F = ?
W = F × S
68Nm = F × 8m
68Nm / 8m = F
8.5N = F
Displacement, S = 8m
Force, F = ?
W = F × S
68Nm = F × 8m
68Nm / 8m = F
8.5N = F

As per the question, the work was done by a compressed spring = 68 J whereas the total distance of the displacement will be 8 m.
The formula that is used is,
Work was done = Force exerted * displacement of the system
68 J = Force exerted * 8 m
Force exerted = 68 J/ 8m
F = 8.5 N
