 Homework Statement
 Unknown object has a mass of 3.2kg on steel plank.
Add force:
FA=22.8N
a=3.02m/s^2
What is the material?
 Relevant Equations
 Newton's Second Law  sum of all forces = mass * acceleration = ...
GR (bold = mathematical convention)
m = 3.2kg
applied force = + 22.8 N
acceleration = + 3.02 m/s^2
FBDhypothetical
^ normal force

friction force <*> applied force

gravitational force
A
ma = FA + FfK
ma = FA Mmg
ma/mg = FA  M
ma/mg  FA = M
m = 3.2kg
applied force = + 22.8 N
acceleration = + 3.02 m/s^2
FBDhypothetical
^ normal force

friction force <*> applied force

gravitational force
A
ma = FA + FfK
ma = FA Mmg
ma/mg = FA  M
ma/mg  FA = M
