A 50.0-kg block and 100-kg block are connected by a string as in the figure shown here. The
pulley is frictionless and of negligible mass. The coefficient of kinetic friction between the 50-kg
block and incline is 0.250. Determine the change in the kinetic energy of the 50-kg block as it
moves from A to B, a distance of 20.0 m.
