On a frictionless air track, cart A hits cart B moving at a velocity of 2 miles per second to the right. Which answer predicts what will happen?

deez nuts is right

Shavoncia is wrong it is Cart A will bounce to the left while cart B will move right at less than 2 meters per second.

Y'all are both wrong.

D. Cart A will bounce to the left while cart B will move right at less than 2 meters per second.

To predict what will happen when cart A hits cart B on a frictionless air track, we can use the principle of conservation of momentum. The total momentum before the collision should equal the total momentum after the collision.

Let's assume that cart A has a mass of mA and is moving with a velocity of vA, and cart B has a mass of mB and is initially at rest (velocity vB = 0).

Before the collision, the total momentum is given by:
Total momentum before = (mass of cart A) * (velocity of cart A) + (mass of cart B) * (velocity of cart B)
= mA * vA + mB * vB
= mA * vA + mB * 0
= mA * vA

After the collision, the total momentum is given by:
Total momentum after = (mass of cart A) * (velocity of cart A) + (mass of cart B) * (velocity of cart B)
= mA * (final velocity of cart A) + mB * (final velocity of cart B)

Since the air track is frictionless and there is no external force acting on the system, the total momentum is conserved. This means that the total momentum before the collision should equal the total momentum after the collision. Hence, we have:

mA * vA = mA * (final velocity of cart A) + mB * (final velocity of cart B)

Given that cart A hits cart B moving at a velocity of 2 miles per second to the right, we can substitute the values into the equation and solve for the final velocities.

This equation alone does not provide enough information to predict exactly what will happen after the collision. Further details about the masses of the carts and the nature of the collision (whether it is an elastic or inelastic collision) would be required to make a more accurate prediction.

and ....

Cart A will stop moving and cart B will move to the right at more than 2 miles per second.
