There is no simple formula for the force. There are simple formulas for the energy or work. The kinetic energy in the car has to equal the energy used as the car is deformed (wrecked), the wall deforms or is damaged, and the movement of the car (momentum) after impact. Conservation of Energy, Conservation of Momentum, and methods such as Virtual Work can be used but the actual analysis is complicated since it is hard to calculate how much energy goes to deforming the car versus the other energy absorbers.
