Up the Ramp The coefficient of kinetic friction between the ramp and the block is 0.23. At point B, the block comes to rest. a, S W + 2s F = l dS W + 2ds F = 0 (1) Assuming that the block moves upwar d 1.5 m, then dS W = -1.5 m since it is directed in the negative sense of S W. Substituted this value into Eq. There is friction between the ramp and the block as it slides a distance x up the ramp and then slides back down. At which position does the block have the greatest kinetic energy? The kinetic friction force is parallel to the ramp and the block's weight has a component parallel to the ramp.
