A 50 kilogram block and a 100 kilogram block are connected by a string running over a negligible pulley therefore that the 100 kilogram mass are hanging free and the 50 kilogram mass is sitting on an incline of 37o. Coefficient of kinetic friction for 50 kilogram block/incline is 0.25. Compute the change in kinetic energy in the 50 kilogram block as it moves 20 meter up the incline (20 meter measured along the incline).
