... the force required to stop a 27 kg child travelling at 25 m/s? Momentum is equal to mass times velocity and impulse is equal to the change of momentum. Using the derived formula from the previous statement F * t = m * Vf - Vi we see that the force exerted on the child by the seatbelt is 1687.5 Newtons which is the equivalent of 172.4 kg. This force ... indirectly proportional to the mass we can see how the force on an adult travelling at the same speed will experience a different force than that of the child. From the formula derived from Newton's second law, F=m*a we see that a 67.5 kg...
