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.

What do you think?

Your options 2 and 5 lack numbers.

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) ???

1) True. Crumple zones on cars are indeed designed to absorb kinetic energy during a collision, converting it into deformation and lengthening the collision time. This reduces the force experienced by the driver.

2) False. Momentum is calculated by multiplying an object's mass (m) with its velocity (v). So, if car one has a mass m1 and a speed v1, and car two has a mass m2 and a speed v2, their momenta would be different unless m1 equals m2 and v1 equals v2.

3) False. According to Newton's third law of motion, the forces exerted on two objects in a collision are always equal in magnitude but opposite in direction. Therefore, the force exerted by car 1 on car 2 is equal in magnitude to the force exerted by car 2 on car 1.

4) True. In a collision, the impulse experienced by an object is equal to the change in momentum. If two identical cars collide head-on with the same speed, the change in momentum for each car would be the same as if one car had collided with a concrete wall. Impulse is determined by the rate of change of momentum, which remains constant regardless of the presence of another car.

5) False. This is a repetition of the statement from question 2. The same explanation applies - unless the masses and speeds are equal, the momenta of the two cars will not be the same.
