Hey, i have this big packet filled with questions i don't know the answers to, but me and my friends have been able to knock out all but three, so i figured i'd ask the brilliant minds that make up this great community for help ;) A hungry squirrel of negligible size (mass m= 2.0 kg) is sitting on the edge of a circular disk of radius R = 2.0 m and mass M=3.0kg. The disk is rotating frictionlessly with a rotational velocity wo=1.0 rad/sec. At the center of the disk is placed a walnut and the squirrel tries to reach the center to get it. A) Suppose the squirrel moves radially toward the center. When he comes to the distance r=1.0m from the center, he stops. What is the angular velocity of the disk? B) At r=1.0m, what is the centripetal acceleration of the squirrel? C) Suppose the static coefficient of fiction between the squirrel and the disk is uS=.5. At r=1.0m, does the squirrel slip? There's one of the three for you guys to munch on, I'll post the others if help on this can be given (they are all about Rotation). (not answers per say, just how to approach the problem, formulas to use, we REALLY REALLY don't know how to do this so any and all help would be appreciative!). Thanks in Advanced!
