SUMMARY
The minimum force required to overcome friction on a 20 kg wooden box pushed across a horizontal stone floor is calculated using the coefficient of kinetic friction, which is 0.40. The force of friction can be determined using the formula F_friction = μ * N, where μ is the coefficient of kinetic friction and N is the normal force. Given that the normal force equals the weight of the box (N = mass * gravity), the minimum force required is 78.4 Newtons.
