An object, previously at rest, slides #5 m# down a ramp, with an incline of #(3pi)/8 #, and then slides horizontally on the floor for another #12 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?
slant height of the ramp
Angle of inclination of the ramp
Length of horizontal floor
vertical height of the ramp
Mass of the object = m
Now applying conservation of energy
Initial PE = work done against friction
