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
