2) A box decelerates as it moves to the right along a horizontal surface as shown in the diagram.
Draw a vector that best represents the force of friction on the box.
3) Sand is often placed on an icy road because the sand
a) decreases
the coefficient of friction between the car and the road
b) increases
the coefficient between the car and the road
c) increases
the normal force of the car on the road
d) decreases
the normal force of the car on the road
4) A different force is applied to four
1-kg blocks to slide them across a uniform level surface at constant speed, 2N, 3N, 4N & 5N. On which box is the
coefficient of friction the smallest? What is it?
5) Jill is pulling 200-N sled through the snow at a
constant speed with a constant horizontal force of 10-N. What is the
coefficient of friction between the sled and the snow? How much force would Jill have to apply in order to accelerate at a rate of 2 m/s/s?

This weekend you will be working on your chapter challenge video.
By Monday, please have your video clip(s) picked out and at least 5 moments where laws of motion are being represented. Be specific! For example, don't just say, "here a ball is being kicked with force" - know, in detail, how the force is being applied to the object. You should also decide who will be speaking about each topic/example.
Here is a program that you can use to make your video:
http://us.onlinevideoconverter.com/
I WILL SHOW YOU HOW TO USE THIS PROGRAM IS CLASS ON MONDAY. If you've never used it before, don't try it this weekend. If you have a video converter that you already use, that is, of course, fine.
Each person will be graded on this project individually, not as a group. I need to see your contribution for you to get any credit. (In your script/video, you are responsible for the content you speak about).
Here are the groups:
1) Frank M, Kyle S, Joe C
2) Johnny D, Liam D, Hunter B
3) Shane C, Kevin C, Victor V
4) Mike Z, Pat L, George K
5) Mark W, Eddie C, Chris N
6) Brian C, Anthony F, Christian B
7) Christian T-S, Jackson H, Brian D
8) Mike P, Carson C, Peter G
**Rubric can be found at the bottom of the page!**
Have fun and think outside the box!

Read the Physics Talk on pages 177-178 and answer the Checking Up questions (1-3).
Monday, April 15
Answers to the Physics to Go questions:
1) Since an object in motion tends to stay in motion, the ball will keep rolling at a constant speed for as long as the surface remains horizontal.
2) The ball will reach a vertical height of 20 cm before it begins to roll down again.
3) It does not seem possible to eliminate friction to arrive at perpetual motion in the real world, except perhaps in deep space far away from the influence of any source of gravity (aka any object with mass).
4) Because the ice exerts almost no frictional force on the hockey puck, the puck will continue to slide with almost constant speed in a straight line until a force is exerted upon it. If the object it hits exerts a force in the direction opposite its motion, the puck will slow down, stop, or even change direction depending upon the nature of the force. If the force is in another direction, the puck's direction and possibly its speed will change due to the force.
For tonight:
1) For question #1, give a short explanation why each choice IS an example of inertia
2) Complete the rest of the worksheet following the original directions.
**Heads up: Quest on Thursday**

Gents,
I'm sorry I cannot be with you again today.
Today, you will have the first few minutes of class to talk to one another about last night's homework. Then, you will work on the two quia assignments; the link to both can be found below. These will not be graded, they are just to help you review. Please make sure that you treat the computers with the same amount of respect and maturity that you would if I was there. You are ambassadors to our room today, and I know you will act accordingly.
1) Quiz 15.
This 'quiz' can be taken an unlimited amount of times. Keep taking it until you get a 100%!
2) Section 1.3 Matching.
This is a game; again, keep playing until you know all the answers well!
Both can be found here:
http://www.quia.com/pages/jtanzman11/activephysics
***Important:
If your computer is having internet trouble, try restarting it.
Also, please make sure you SHUT DOWN your computer at the end of class - DON'T just log off.

Work on these problems in your notebook: (don't forget v = d/t !!)
1)In last week's Homecoming victory, Al Konfurance, the star halfback of South's football team, broke a tackle at the line of scrimmage and darted upfield untouched. He averaged 9.8 m/s for an 80-yard (73 m) score. Determine the time for Al to run from the line of scrimmage to the end zone.
2)Ken Runfast is the star of the cross-country team. During a recent morning run, Ken averaged a speed of 5.8 m/s for 12.9 minutes. Ken then averaged a speed of 6.10 m/s for 7.1 minutes. Determine the total distance which Ken ran during his 20 minute jog.
3) In the qualifying round of the 50-yd freestyle in the sectional swimming championship, Dugan got an early lead by finishing the first 25.00 yd in 10.01 seconds. Dugan finished the return leg (25.00 yd distance) in 10.22 seconds.
a. Determine Dugan's average speed for the entire race.
b. Determine Dugan's average speed for the first 25.00 yd leg of the race.
c. Determine Dugan's average velocity for the entire race.
Use the graph to determine the speeds at which the two students move. (Ignore any stationary periods of time.) Then determine how much faster the fastest student moves than the slower student.

In our investigate, Method B, you tested your reaction time by catching a ruler. You were also timing this part of the experiment with a stopwatch (another test of reaction time!). Let's find out how accurate you were!
Using the distances you recorded (NOT THE TIMES), use the following equation to calculate how long the ruler was falling.
d = distance the ruler falls (in cm)
g = acceleration of the ruler due to gravity (980 cm/s2)
Now, compare your calculated times to the times you recorded during your investigate. Are they the same? Why or why not?
