Two 110 kg bumper cars are moving toward each other in opposite directions. car a is moving at 8 m/s and car z at –10 m/s when they collide head–on. if the resulting velocity of car a after the collision is –10 m/s, what is the velocity of car z after the collision?

Explanation:

Mass of bumper cars,

Initial speed of car A,

Initial speed of car Z,

Final speed of car A after the collision,

We need to find the velocity of car Z after the collision. Let it is equal to . Using the conservation of momentum as :

So, the velocity of car Z after the collision is (-12 m/s). Hence, this is the required solution.

it has to be b, about 97 percent.

there are no components of a physical goal mentioned on the list of choices that you've provided.
