1. The problem statement, all variables and given/known data The 9 N cradle is supported as shown by two uniform disks that roll without slipping at all surfaces of contact. The weight of each disk is w=6 N and the radius of each disk is r=10 cm. knowing that the system is initially at rest, determine the largest velocity Vc of the cradle, for the three cases shown below, after it has moved 45 cm. [PLAIN]http://www.pimpmyshu.com/images/stories/dyn1.jpg [Broken] I'm having trouble getting started with this question so I was hoping for some advice on what areas to look into that would help with this question and where I could find relevant equations etc that I could use to solve it.
