Please help with number 17

Problem 16-17: Four objects, each of mass m are attached to a disk of mass M and radius R as shown. Each object is at a distance 1: from the axis of the disk. The system is initially at rest on a frictionless flat surface. A string is would around the disk and such that when the end of the string pulled with a constant force I", the disk both rotates and translates. When the end of the string is pulled a distance w + d, the center of mass of the disk (and 4 masses attached to it] has translated a distance d. Problem 16: [6 points] What is the translational kinetic energy of the system?
