A m1 = 47.0 kgblock and a m2 = 100.0 kg block are connected by a string as inFigure P8.36. The pulley is frictionless and of negligible mass.The coefficient of kinetic friction between the 47.0 kg block and incline is 0.250. Determine the change in the kinetic energy of the 47.0 kg block as it moves from A to B, a distance of 20.0 m.
