Please decide which of the following statements for car collisions are true or false.
1)Crumple zones on cars are parts of the front of the car that are designed to receive maximum deformation during a head-on collision. The essential safety benefit of crumple zones results from absorbing kinetic energy, converting it into deformation, and lengthening the effective collision time, thus reducing the average force experienced by the driver.
2) If car one has a mass and a speed , and car two has a mass of speed , then both cars have the same momentum.
Car 1 has a mass , and car 2 has a mass . 3)In a two-car head-on collision of these cars traveling with identical speeds in opposite directions, car 2 exerts twice the force on car 1 than car 1 exerts on car 2.
4)If two identical cars with identical speeds collide head-on, the magnitude of the impulse received by each car and each driver is the same as if one car at the same speed had collided head-on with a concrete wall.
5)If car one has a mass and a speed , and car two has a mass of speed , then both cars have the same momentum.

  2. 1) It's correct.
    2) ???
    3) No both cars get the same force.
    4) wrong again. It's equal to the impulse of one car at twice the speed had collided head-on with a concrete wall.
    5) ???
