Question

which collision presents the greater possibility of danger to the passenger involved two cars colliding and remaining entangled or the same two cars colliding and rebounding off each other

Answer 1

I think , that the Passengers involved in the first case will face more force as rebounding helps to make the momentum equal , whereas in the first case rebounding doesn't occur , so , the force must have been , passed on to the passengers bodies , overall first force is more dangerous .

Answer 2

Elastic collision

Elastic collision presents the greater possibility of danger to the passenger involved two cars colliding and remaining entangled or the same two cars colliding and rebounding off each other.

• The force integral and the impulse values calculated using the velocity-change formula agreed. Almost twice as much energy was released during the elastic impact than during the inelastic collision.
• A collision between two bodies in physics is referred to as an elastic collision if their combined kinetic energy stays constant. There is no net conversion of kinetic energy into other forms, such as heat, noise, or potential energy, in an ideal, fully elastic collision.
• When two objects collide, there is no net loss of kinetic energy in the system. This is known as an elastic collision. In elastic collisions, kinetic energy and momentum are both conserved.
• When a moving item of the same mass collides with a stationary object, the stationary object experiences a higher change in momentum. A stationary object strikes a moving object in a collision; the stationary object has a lot less mass. The force of impact is larger against the stationary item.
