Physics Should cars have bumpers that collapse under impact? Yes, since they help to absorb the impact of a collision and keep the occupants safe Yes, since the offending car should get damaged and pay for the mistake No, since the colliding car would then ram into the occupants and kill them No, since it would be very expensive to get the car repaired Yes, since they help to absorb the impact of a collision and keep the occupants safe Yes, since the offending car should get damaged and pay for the mistake No, since the colliding car would then ram into the occupants and kill them No, since it would be very expensive to get the car repaired ANSWER DOWNLOAD EXAMIANS APP
