Question
A hockey puck of mass .2kg is sliding down an inclined plane with an angle of 15 degrees to the horizon. If the puck is moving with a constant speed, what is the coefficient of kinetic friction between the puck and the plane?
Answers
mgsinα=F(fr) = μN= μmgcosα
sinα= μcosα
μ=tanα
sinα= μcosα
μ=tanα
