Momentum and Collision Quiz

What is the initial condition of the alpha particle before the collision?

• It is moving in a circular path.

• It is stationary.

• It is moving vertically.

• It is on a collision course with particle Y.

Why is the initial Y component of momentum considered zero?

• Because the alpha particle is stationary.

• Because the initial momentum is purely vertical.

• Because particle Y is moving.

• Because the initial momentum is purely horizontal.

How is the Y component of momentum for the alpha particle calculated?

• By adding its mass to velocity and sine of 65 degrees.

• By multiplying its mass with velocity and cosine of 65 degrees.

• By dividing its mass by velocity and sine of 65 degrees.

• By multiplying its mass with velocity and sine of 65 degrees.

What is the formula used to find the final momentum of particle Y?

• Mass of alpha particle times 258 times sine of 65 divided by sine of 25.

• Mass of alpha particle times 258 times cosine of 25 divided by sine of 65.

• Mass of alpha particle times 258 times cosine of 65 divided by cosine of 25.

• Mass of alpha particle times 258 times sine of 25 divided by sine of 65.

What is a common mistake when solving momentum problems in this context?

• Not considering the conservation of momentum in the X direction.

• Using the wrong angle for calculations.

• Forgetting to convert units.

• Ignoring the mass of the particles.
