Physics Homework Help (10/20/10)

Homework is Due:TOMMORROW!! Here it is if you need to print out a copy again.
Force Calculations
Force Diagrams

Here is the help....

#13 on Force Calculations

Given a Force of 100N and an acceleration of 5 m/s2, what is the mass?

STEP 1: Identify Variables
F = 100N a = 5 m/s2 m = ?

STEP 2: Identify useful equations
If F = ma then with some algebra rearranging, m = F/a

STEP 3: Plug in variables
m = 100N /5 m/s2

STEP 4: Solve
m = 20 kg

Ch.4 Activity 1 MAKE-UP Assignment

Physics Students -
Those of you that had a "m" (m=missing) or an "i" (i=incomplete) on your grade report last week for "Ch.4 Act.1" can complete the following online assignment to make-up those points.

To get your points back for the missing Ch.4 Act.1 work, click on the following website links on the words "velocity" and "acceleration" and read the information on the website. After reading, complete the quizzes for each. When you are directed to the website, scroll down to "Lesson 1: Mechanics" and click on "2. Velocity" and "3. Acceleration"

1) Velocity - After reading the information on the website, take the Ch.2 Quiz (link at the bottom) of the page and either email me your answers or print them out and turn in.

2) Acceleration - After reading the information on the website, take the Ch.3 Quiz (link at the bottom) of the page and either email me your answers or print them out and turn in.

If you have any questions post a comment on this post.
- Mr. Cram
