A body slipping on a rough horizontal plane moves witha deceleration of 4.0 m/s. What is the coefficient ofkinetic friction between the block and the plane?. |
|
Answer» The friction force causing the deceleration = f = m.a Where m = mass of the body, and a = deceleration of the body = 4.0 m/s² So f = 4m N Normal force on the body = weight of the body = mg N So coefficient of kinetic friction = 4m/mg =4/g = 4/9.8= 0.4 |
