Car Crash Calculator

Assuming the weight of the driver is 70 kg, we can calculate the impact forces in two situations: Without the seatbelt, the stopping distance would be 4 cm, and the impact force is: F = 70 kg × (44.44 m/s)²/(2 × 0.04 m) = 1728 kN; With the seatbelt on, the stopping distance increases to 20 cm. The force becomes:
