Assume magic land conditions on all problems unless stated
otherwise. In other words there is no air resistance or friction. |

1 |
) |
- An object accelerates downward at 3 m/s/s what is the
direction of the net force acting on the object?
Downward. The net force and acceleration go in the same
direction
|
|
2 |
) |
- An object is displaced 90 meters to the north. What is the
direction of the object's average velocity?
To the north.
The displacement and velocity go in the same direction.

3 |
) |
- What is the relationship of the magnitudes of a vectors
components?
Independent
|
|
4 |
) |
- What is the relationship of the directions of a vectors
components?
Right angles. Remember, components align with either the x, y,
or z axis.
|

5 |
) |
- A vector has a y-component of 23 N and an x-component of -
37 N. Find the vector's magnitude.
Magnitude = 43.6
|

6 |
) |
- If a ball is throw with a velocity of 50 m/s at an angle
of 37 degrees above the horizontal, what is its horizontal velocity
component?
40 m/s
|
|
7 |
) |
- When adding two vectors, the resultant will be greatest
when the angle between the two vectors is _________________.
0 degrees, They're in the same dimension and going in the same
direction.
|
|
8 |
) |
- The x-component of a vector = 30 and the y-component = 40.
Find the angle of the resultant vector.
53 degrees
|
|
9 |
) |
- You have a 12 N force and a 5 N force. When they are added
together, what are the maximum and minimum magnitude possible forces? Assume you can
manipulate the angle.
Max = 17, min = 7

) |
- Calculate the minimum time for Running Bear to swim across
a raging river with a current of 2.5 m/s if he can swim at 2.0 m/s and the
raging river is 100 m wide.
Min time = 50 sec
|
|
11 |
) |
-
Calculate the time for Running Bear to swim straight across
a raging river with a current of 1.5 m/s if he can swim at 2.0 m/s and the
raging river is 100 m wide.
- Time
= 76 sec
