A weird wind phenomenon causes all the fallingsnowflakes to stop and be completely stationary. You throw asnowball, and it sticks to and collects the snowflakes it hitsduring its flight, growing bigger on the way. Neglecting airresistance, compare the momentum of the original snowball at thebeginning of its flight to the momentum of the bigger snowball atthe end of its flight.
A) The bigger snowball will have a larger momentum because ithas a higher mass.
B) The original snowball had the larger momentum because it wasmoving faster before it got slowed down by hitting thesnowflakes.
C) The original and bigger snowballs each have the samemomentum.
D) The bigger snowball will have more momentum because it willhave more energy.
As a packing crate accelerates down an inclined ramp, gettingfaster and faster, its momentum
A) increases, because the force of gravity is acting on it.
B) decreases because it is going toward the Earth.
C) does not change because momentum is always conserved.
D) does not change because there is no collision that hasoccured.
Consider a "system" of two cars driving towardeachother on a collision course. Select all of the following thatcould be true:
a. The cars could collide, and stick together, remaining exactlyat the point of collision, with kinetic energy not being conserved(quickly going to zero).
b. The cars could collide and stick, and together skid down theroad
c. The velocity of the center of mass of the two car system willbe the same directly before and directly after the collision.
d. Neglecting friction, the total momentum of the two car systemwill decrease immediately after the collision.
e. Neglecting friction, the total momentum of the two carsystem will increase immediately after the collision.
Hint: Is momentum conserved in a collision?
