So, if your car has a “good” frontal crash score, and you collide with another vehicle of equal or lesser weight head on at 40 mph, your odds of survival are close to 100%. Fig. Before the collision, the momentum of the car is +20000 kg.m/s and the momentum of the truck is -60000 kg.m/s; the total system momentum is -40000 kg.m/s. Show that the colliding ball loses 8/9 th of its energy after collision. Another type of tripped rollover occurs due to a collision with another vehicle or object. This is called collision in one dimension. In a head-to-head car accident, the momentum is transferred from one car to the other, but so much force is applied that the car structure cannot handle it, this is why a car wrecks. Note: The momentum of the bodies is conserved only when there is no friction on the surface or air resistance. Physics Notes of Class 11 are well formatted and provided with best way of derivations.
