Homework Statement A block of wood is sitting on an inclined plane. One end of the plane is rised until the wood block slides down. The wood block slides down when the plane has an angle of 17.157 degrees . What is the coefficient of friction? Homework Equations F/R The Attempt...

Post Question: If the coeffiencent of friction is F/R, what do you substitute into find F and R? -------------------------------------------------------------------------------- has anybody come across this formula before? is there another way to calculate the gain in potential energy

the full question is what is the coeffiecent of friction between the two surfaces

working attached as picture

what am i missing :? this is way above anything iv been taught and the formula isn't explained well on google :(

co-efficient of friction (µ) = F/R F is work done by the applied force - gain in potential energy R is mass x gravity x cos (angle of incline) I calculated work done by the applied force by: force x distance where the force = mass x 9.81 I calculated gain in potential energy by mass x...

basically I am trying to find the coefficient of fricition between two wooden surfaces but I am struggeling with the equation :-)

work done by the applied force work = force x distance = ? in joules gain in potential energy of the block mass x change in height (work done by force - gain in potential energy) / (MG cos angle) the mass of my block was 0.3389kg mass x 9.81 = 3.324609 distance of 214.60 cm...
