Detailed explanation-1: -In a collision of two cars of unequal mass, the occupants of the lighter car would experience much higher accelerations, hence much higher forces than the occupants of the heavier car. conditions is called potential energy .
Detailed explanation-2: -The forces in a collision are quadrupled when the speeds are doubled, because kinetic energy increases with the square of velocity, according to Newton’s formula.
Detailed explanation-3: -They will both come to a stop at the point of the collision. Thus each car will go from 60 to 0. Each car will behave exactly the same as if it had hit a VERY strong stationary wall at 60 MPH-The same deceleration and the same damage.
Detailed explanation-4: -When a truck and a car collide, the impact of the crash will be considerably greater in the car, because the mass of the truck is so much larger, and therefore will take much longer to stop. This means that the G force in the car will be much higher as it goes from moving to a full stop in a shorter period of time.
