**Question: What is momentum?**

Options:

- ○ mass times velocity
- ○ none of the given answers is correct
- ○ mass times velocity squared
- ○ velocity divided by mass
- ○ mass divided by velocity

*Explanation:*

Momentum, in physics, is defined as the product of an object's mass and its velocity. Thus, the correct answer is "mass times velocity."

**Physics Question: Momentum Change in Deflected Motion**

A puck, moving at 20 m/s East, deflects off the goalie so that it then moves at 15 m/s North. What is the magnitude of the change of momentum of the puck caused by the deflection? (in units of kg·m/s)

- ○ 1000
- ○ 5
- ○ 2
- ○ 10
- ○ none of the given answers is correct

**Explanation:**
To solve for the change in momentum, which involves a change in direction, use the following vectorial approach:

1. Calculate the initial momentum vector (East direction).
2. Calculate the final momentum vector (North direction).
3. Determine the change in momentum, which is the vector difference between the final and initial momentum vectors.
4. Use the Pythagorean theorem to find the magnitude of the resultant vector.

(Note: This explanation assumes mass is given or can be ignored for the purpose of identifying a unit vector change.)
