Which one of the following statements best explains why an air bag reduces the likelihood of injury? 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. Veving Saved Work Reverto Loast Resononse Two objects of equal mass undergo a perfectly inelastic collision. Before the collision, one object is moving north and the other is moving east. You may assume that there are no external forces acting 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

`2m`

, moving eastward with a speed of

`u`

, has the same momentum as an object of mass

`m`

moving eastward with a speed of

`2u`

. An object of mass

`2m`

, moving eastward with a speed of

`2u`

, has the same momentum as an object of mass

`m`

moving eastward with a speed of

`u`

. Two objects of the same mass and moving with the same speed in opposite directions have the same momentum. 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.
