PROBLEM 6: A concrete bucket weighing 65kg is hanging from a cable of negligible weight over a frictionless pulley. The bucket is connected to a distribution box with weight equal to 80kg that rests from a horizontal surface carrying a 50kg bag of gravel. If the coefficient of static and kinetic friction between the box and the surface is 0.70 and 0.40, respectively, and if the bag of gravel is picked up, find the speed of the bucket after it has descended 2m from rest.
