In a perfectly inelastic collision between two objects... the final velocity of both objects is the same. the objects move in opposite directions after the collision. kinetic energy is conserved. on the objects during the collision. Which one of the following choices is the only possible outcome of the collision? Both objects move in a direction at some angle north of east. Both objects move directly east after the collision. Both objects move directly north after the collision. Which one of the following statements concerning momentum is true? An object of mass , moving eastward with a speed of , has the same momentum as an object of mass moving eastward with a speed of . An object of mass , moving eastward with a speed of , has the same momentum as an object of mass moving eastward with a speed of Two objects of the same mass and moving with the same speed in opposite directions have the same momentum. Which one of the following statements best explains why an air bag reduces the likelihood of injury? The air bag reduces the average force that occurs during the collision. The air bag reduces the change of momentum that occurs during a collision. The air bag reduces the time interval over which the change of momentum occurs during a collision. Viewing Saved Work Revert to Last Response Two objects of different masses collide. Which one of the following statements is FALSE? During the collision, the acceleration of object 2 is equal and opposite to the acceleration of object 1. The change of momentum of object 1 is equal and opposite to the change of momentum of object 2. During the collision, the force on object 2 exerted by object 1 is equal and opposite to the force on object 1 exerted by object 2 . Consider a collision between two objects. If the net external force acting on the objects is zero, then... the total momentum of the two objects is conserved but the total kinetic energy of the two objects is not necessarily conserved. the total momentum of the two objects and the total kinetic energy of the two objects are conserved. the total momentum of the two objects is not conserved but the total kinetic energy of the two objects is conserved.
