A person in a head-on car collision, who is not wearing a seatbelt, continues to move forward at the original speed of the car
Madhur L.
Seatbelts provide two main advantages in a car accident: (1) they keep you from being thrown from the car, and (2) they reduce the force that acts on you during the collision to survivable levels. This second benefit can be illustrated by comparing the net force encountered by a driver in a head-on collision with and without a seat belt. 1) A driver wearing a seat belt decelerates at roughly the same rate as the car itself. Since many modern cars have a "crumple zone" built into the front of the car, let us assume that the car decelerates over a distance of 1.1 m. What is the net force acting on a 73 kg driver who is driving at 18 m/s and comes to rest in this distance? F_with belt = 2) A driver who does not wear a seat belt continues to move at the initial velocity until he or she hits something solid (e.g., the steering wheel) and then comes to rest in a very short distance. Find the net force on a driver without seat belts who comes to rest in 1.2 cm. F_without belt =

A friend claims that, as long as he has his seat belt on, he can hold on to a 12.0 -kg child in a $60.0 \mathrm{mi} / \mathrm{h}$ head-on collision with a brick wall in which the car passenger compartment comes to a stop in 0.050 0 s. Show that the violent force during the collision will tear the child from his arms. A child should always be in a toddler seat secured with a seat belt in the back seat of a car.
