During a demolition derby, vehicle 1 collided vehicle 2 going in the opposite direction and came to an immediate stop. If the vehicles are of different masses and were not travelling at the same velocity, what can be concluded about them? *

Their change in momentum is the same in magnitude and opposite in direction

Explanation:

The momentum of an object is defined as:

where

m is the mass of the object

v is the velocity of the object

Therefore, the change in momentum of an object is

where is the change in velocity.

During a collision, the force experienced by an object is equal to the rate of change of momentum:

where is the duration of the collision.

According to Newton's third law of motion, the force exerted by vehicle 1 on vehicle 2 during the collision is equal (and opposite) to the force exerted by vehicle 2 on vehicle 1, so

Which means

And since the duration of the collision is the same for the two vehicles, this becomes

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
