Question

How are momentum and impulse related?  

Question 1 options:

	They are not related
	Impulse is equal but opposite to momentum
	Impulse is equal to the change in momentum
	Impulse is equal to momentum

What do we mean by the statement that momentum is a vector?

Question 2 options:

	You may assign negative numbers to vectors in the opposite direction.
	All of these are true.
	When you add momentums, the direction is important, and negative numbers or trig may be needed.
	Momentum has magnitude and direction.

Before a shotgun is fired, there is a total momentum of zero. Assuming it is a conservative system, how can you explain the increase in speed of the bullet, which gives the bullet a non zero momentum?

Question 3 options:

	Momentum is not a vector, so the change in speed is not important.
	The impulse is much less than the recoil, so the momentum at the end must be greater than the momentum at the beginning.
	There is zero speed and zero momentum at the beginning, so the momentum at the end is zero. The gun kicks in the opposite direction, so the momentums must cancel to zero.
	The momentum, recoil, and impulse all add to the new momentum at the end.
